The special case where a destabilizing temperature gradient counteracts the action of a stabilizing gradient in molecular weight is of interest to astrophysics (inside stars and giant planets) and geophysics (lakes, oceans) as well as to some engineering applications. The detailed dynamics of such a system depend on the molecular diffusivities of heat, momentum, and solute as well as system parameters including the ratio of the two gradients to each other. Further important properties are the formation and merging of well-defined layers in the fluid which cannot be derived from linear stability analysis. Moreover, the physical processes operate on a vast range of length and time scales. This has made the case of semi-convection, where a mean temperature gradient destabilizes the stratification while at the same time the mean molecular gradient tends to stabilize it, a challenge to physical modelling and to numerical hydrodynamical simulation. During the MetStr{\"o}m project the simulation codes ANTARES and MITgcm have been extended such that they can be used for the simulations of such flows. We present a comparison of effective diffusivities derived from direct numerical simulations. For both stars and the oceanic regimes, the Nusselt numbers (scaled diffusivities) follow similar relationships. Semi-convection quickly becomes inefficient, because the formation of layers limits vertical mixing. In contrast to the complementary saltfingering, these layers tend to damp instabilities so that effective diffusivities of salinity (concentration) are up to two orders of magnitudes smaller than in the former case.}, language = {en} } @misc{SeeligKielczewskiTuliszkaSznitkoetal., author = {Seelig, Torsten and Kielczewski, Kamil and Tuliszka-Sznitko, Ewa M. and Harlander, Uwe and Egbers, Christoph and Bontoux, Patrick}, title = {Taylor-Couette flow with asymmetric end-walls boundary conditions}, series = {15th European turbulence conference (ETC), Delft, The Netherlands (2015)}, journal = {15th European turbulence conference (ETC), Delft, The Netherlands (2015)}, language = {en} } @misc{EgbersGorenzSchmidtetal., author = {Egbers, Christoph and Gorenz, Paul and Schmidt, Marcus and Wolf, Carsten}, title = {3-D-CFD-Simulation der Schmierspaltstr{\"o}mung in einem Radialgleitlager}, series = {Motortechnische Zeitschrift : MTZ}, volume = {76}, journal = {Motortechnische Zeitschrift : MTZ}, number = {7-8}, issn = {2192-8843}, pages = {66 -- 73}, language = {de} } @phdthesis{Christl, author = {Christl, Andreas}, title = {3D-CFD-Simulation der exzentrischen Taylor-Couette Str{\"o}mung mit Bezug auf das hydrodynamische Gleitlager}, publisher = {Cuvillier}, address = {G{\"o}ttingen}, isbn = {978-3-73699-081-4}, pages = {II, 109}, language = {de} } @phdthesis{Koenig, author = {K{\"o}nig, Franziska}, title = {Investigation of High Reynolds Number Pipe Flow}, publisher = {Cuvillier}, address = {G{\"o}ttingen}, isbn = {978-3-73699-049-4}, language = {en} } @inproceedings{SeeligHarlanderKielczewskietal., author = {Seelig, Torsten and Harlander, Uwe and Kielczewski, Kamil and Tuliszka-Sznitko, Ewa M. and Bontoux, Patrick and Egbers, Christoph}, title = {Study of transitional and turbulent flows in rotor/stator cavities}, series = {ICTW 19, Book of Abstracts, 19th International Couette-Taylor Workshop, June 24 - 26, 2015 Cottbus, Germany}, booktitle = {ICTW 19, Book of Abstracts, 19th International Couette-Taylor Workshop, June 24 - 26, 2015 Cottbus, Germany}, address = {Cottbus}, pages = {118 -- 119}, language = {en} } @misc{HoffHarlanderEgbers, author = {Hoff, Michael and Harlander, Uwe and Egbers, Christoph}, title = {Experimental survey of linear and nonlinear inertial waves and wave instabilities in a spherical shell}, series = {Journal of Fluid Mechanics}, journal = {Journal of Fluid Mechanics}, number = {vol. 789}, issn = {1750-6859}, doi = {10.1017/jfm.2015.743}, pages = {589 -- 616}, language = {en} } @phdthesis{Dahley, author = {Dahley, Sandy}, title = {Laboratory experiments and numerical simulations of inertial waves in a rotating spherical shell}, publisher = {Cuvillier Verlag}, address = {G{\"o}ttingen}, isbn = {978-3-73699-198-9}, language = {en} } @incollection{OenguenerZanounKoenigetal., author = {{\"O}ng{\"u}ner, Emir and Zanoun, El-Sayed and K{\"o}nig, Franziska and Egbers, Christoph}, title = {Structure Investigation in Pipe Flow at High Reynolds Numbers}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-319-29130-7}, pages = {217 -- 220}, language = {en} } @misc{ZanounOenguenerEgbers, author = {Zanoun, El-Sayed and {\"O}ng{\"u}ner, Emir and Egbers, Christoph}, title = {Conventional measuring probes in the wall layer of turbulent subsonic ducted flows}, series = {Thermophysics and Aeromechanics}, volume = {23}, journal = {Thermophysics and Aeromechanics}, number = {3}, issn = {1531-8699}, pages = {329 -- 342}, language = {en} } @misc{VeenHuismanMerboldetal., author = {Veen, Roeland C.

For the experiment, eight unevenly distributed ultrasonic distance sensors measure the local height of the wave surface. The resonance curves show maxima only for odd multiples of the fundamental resonance frequency . We explained this behavior using a simple intuitive "ping-pong" like model. Collision of wave fronts can be observed for higher frequencies. Also, the wave reflection on the walls can be treated as wave collision with itself. The non-linearity seems to be weak in our study so the delay in the wave propagation before and after the collision is small. Time-space plots show localized propagating waves with high amplitudes for frequencies near resonance. Between the peaks low amplitude and harmonic patterns are observed. However, for higher frequencies, the frequency band for localized waves becomes wider. In the Fourier space-time plane, this can be observed as a point for the harmonic patterns or a superposition of two lines: one line parallel to wave-vector k axis corresponding to the excitation frequency and a second line with inclination given by wave propagation velocity .

For many years scientists try to understand these flows by doing laboratory experiments. In the present paper we discuss two rather new laboratory experiments designed to study certain aspects of the atmospheric circulation. One of the experiments, the differentially heated rotating annulus at the Brandenburg University of Technology (BTU) Cottbus, has a cooled inner cylinder and a heated outer wall. However, the structure of the atmospheric meridional circulation motivates a variation of this "classical" design. In the second experiment described, operational at the Institute of Continuous Media Mechanics (ICMM) in Perm, heating and cooling is performed at different vertical levels that resembles more the atmospheric situation. Recent results of both experiments are presented and discussed. Differences and consistencies are highlighted. Though many issues are still open we conclude that both setups have their merits. The variation with heating and cooling at different levels might be more suited to study processes in the transition zone between pure rotating convection and the zone of westerly winds. On the other hand, the simpler boundary conditions of the BTU experiment make this experiment easier to control.}, language = {en} } @inproceedings{SeeligBorciaKleinetal., author = {Seelig, Torsten and Borcia, Ion-Dan and Klein, Marten and Ghasemi, Abouzar and Will, Andreas and Egbers, Christoph and Schaller, Eberhard and Harlander, Uwe}, title = {Inertial waves and wave attractors in a rotating annulus with inner or outer cylinder libration}, series = {European Geosciences Union (EGU), 10th General Assembly, Vienna, Austria, 07 - 12 April 2013}, booktitle = {European Geosciences Union (EGU), 10th General Assembly, Vienna, Austria, 07 - 12 April 2013}, language = {en} } @misc{MerboldHasanuzzamanBuchwaldetal., author = {Merbold, Sebastian and Hasanuzzaman, Gazi and Buchwald, Tom and Schunk, Christoph and Schmeling, Daniel and Volkmann, Andr{\´e} and Brinkema, Robert and Hampel, Uwe and Schr{\"o}der, Andreas and Egbers, Christoph}, title = {Reference experiment on aerosol particle transport for dynamic situations}, series = {tm - Technisches Messen}, volume = {90}, journal = {tm - Technisches Messen}, number = {5}, issn = {2196-7113}, doi = {10.1515/teme-2022-0118}, pages = {13}, language = {en} } @inproceedings{AlexandrovHarlanderEgbers, author = {Alexandrov, Kiril and Harlander, Uwe and Egbers, Christoph}, title = {Definition und Vergleich von Zust{\"a}nden eines rotierenden Zylinderspalts unter Betrachtung skalenseparierter Str{\"o}mungsstrukturen}, language = {de} } @misc{HasanuzzamanEivaziMerboldetal., author = {Hasanuzzaman, Gazi and Eivazi, Hamidreza and Merbold, Sebastian and Egbers, Christoph and Vinuesa, Ricardo}, title = {Enhancement of PIV measurements via physics-informed neural networks}, series = {Measurement Science and Technology}, journal = {Measurement Science and Technology}, issn = {1361-6501}, doi = {10.1088/1361-6501/aca9eb}, language = {en} } @misc{HarlanderBorciaVinczeetal., author = {Harlander, Uwe and Borcia, Ion-Dan and Vincze, Miklos and Rodda, Costanza}, title = {Probability Distribution of Extreme Events in a Baroclinic Wave Laboratory Experiment}, series = {Fluids}, volume = {7}, journal = {Fluids}, number = {8}, issn = {2311-5521}, doi = {10.3390/fluids7080274}, abstract = {Atmospheric westerly jet streams are driven by temperature differences between low and high latitudes and the rotation of the Earth. Meandering jet streams and propagating Rossby waves are responsible for the variable weather in the mid-latitudes. Moreover, extreme weather events such as heat waves and cold spells are part of the jet stream dynamics. For many years, a simple analog in the form of a simplified laboratory experiment, the differentially heated rotating annulus, has provided insight into the dynamics of the meandering jet stream. In the present study, probability density distributions of extreme events from a long-term laboratory experiment are studied and compared to the atmospheric probability density distributions. Empirical distributions of extreme value monthly block data are derived for the experimental and atmospheric cases. Generalized extreme value distributions are adjusted to the empirical distributions, and the distribution parameters are compared. Good agreement was found, but the distributions of the experimental data showed a shift toward larger extreme values, and some explanations for this shift are suggested. The results indicate that the laboratory model might be a useful tool for investigating changes in extreme event distributions due to climate change.

Direct numerical simulations of the fluid flow in an annular container with librating outer (inner) cylinder side wall and Reynolds-averaged Navier-Stokes (RANS) equations as diagnostic equations are used to investigate generation mechanism of the retrograde (prograde) azimuthal mean flow in the bulk. First, we explain, phenomenologically, how absolute angular momentum of the bulk flow is mixed and changed due to the propagation of the G{\"o}rtler vortices, causing a new vortex of basin size. Then we investigate the RANS equations for intermediate time scale of the development of the G{\"o}rtler vortices and for long time scale of the order of several libration periods. The former exhibits sign selection of the azimuthal mean flow. Investigating the latter, we predict that the azimuthal mean flow is proportional to the libration amplitude squared and to the inverse square root of the Ekman number and libration frequency and then confirms this using the numerical data. Additionally, presence of an upscale cascade of energy is shown, using the kinetic energy budget of fluctuating flow.}, language = {en} } @misc{FuttererDahleyEgbers, author = {Futterer, Birgit and Dahley, Norman and Egbers, Christoph}, title = {Thermal electro-hydrodynamic heat transfer augmentation in vertical annuli by the use of dielectrophoretic forces through a.c. electric field}, series = {International Journal of Heat and Mass Transfer}, volume = {93}, journal = {International Journal of Heat and Mass Transfer}, issn = {0017-9310}, pages = {144 -- 154}, language = {en} } @misc{GrimmStreleKupkaLoewBasellietal., author = {Grimm-Strele, Hannes and Kupka, Friedrich and L{\"o}w-Baselli, Bernhard and Mundprecht, Eva and Zaussinger, Florian and Schiansky, Peter}, title = {Realistic simulations of stellar surface convection with ANTARES: I.

Meridional symmetry is broken by replacing the inner cylinder with a truncated cone (frustum). Waves are excited by individual longitudinal libration of the walls. The geometry is non-separable and exhibits wave focusing and wave attractors. We investigated laboratory and numerical results for the Ekman number E ≈ 10-6. inclination α = 5.71◦ and libration amplitudes ε 0.2 within the inertial wave band 0 < ω < 2Ω0 . Under the assumption that the inertial waves do not essentially affect the boundary-layer structure, we use classical boundary-layer analysis to study oscillating Ekman layers over a librating wall that is at an angle α = 0 to the axis of rotation. The Ekman layer erupts at frequency ω = f∗, where f∗ ≡ 2Ω0 sin α is the effective Coriolis parameter in a plane tangential to the wall. For the selected inclination this eruption occurs for the forcing frequency ω/Ω0 = 0.2. For the librating lids eruption occurs at ω/Ω0 = 2. The study reveals that the frequency dependence of the total kinetic energy Kω of the excited wave field is strongly connected to the square of the Ekman pumping velocity wE (ω) that, in the linear limit, becomes singular when the boundary layer erupts. This explains the frequency dependence of non-resonantly excited waves. By the localization of the forcing, the two configurations investigated, (i) frustum libration and (ii) lids together with outer cylinder in libration, can be clearly distinguished by their response spectra. Good agreement was found for the spatial structure of low-order wave attractors and periodic orbits (both characterized by a small number of reflections) in the frequency windows predicted by geometric ray tracing. For 'resonant' frequencies a significantly increased total bulk energy was found, while the energy in the boundary layer remained nearly constant. Inertial wave energy enters the bulk flow via corner beams, which are parallel to the characteristics of the underlying Poincar{\´e} problem. Numerical simulations revealed a mismatch between the wall-parallel mass fluxes near the corners. This leads to boundary-layer eruption and the generation of inertial waves in the corners.}, language = {en} } @misc{SeeligHarlander, author = {Seelig, Torsten and Harlander, Uwe}, title = {Can zonally symmetric inertial waves drive an oscillating zonal mean flow?}, series = {Geophysical \& Astrophysical Fluid Dynamics}, volume = {109}, journal = {Geophysical \& Astrophysical Fluid Dynamics}, number = {6}, issn = {1029-0419}, doi = {10.1080/03091929.2015.1094064}, pages = {541 -- 566}, language = {en} } @misc{HoffHarlanderEgbers, author = {Hoff, Michael and Harlander, Uwe and Egbers, Christoph}, title = {Empirical singular vectors of baroclinic flows deduced from experimental data of a differentially heated rotating annulus}, series = {Meteorologische Zeitschrift}, volume = {23}, journal = {Meteorologische Zeitschrift}, number = {6}, doi = {10.1127/metz/2014/0563}, pages = {581 -- 597}, language = {en} } @incollection{HarlanderLarcherWrightetal., author = {Harlander, Uwe and Larcher, Thomas von and Wright, G.

Utmost relevance of such experiments, however, is applied in the engineering applications in aerospace and marine industries. In particular, continuous effort is being imparted to explore the underlying physics of the flow in order to develop models for numerical tools and to achieve flow control. Within the scope of this Ph. D. topic, application of active control method such as micro-blowing effect in the incompressible, zero pressure gradient turbulent boundary layer was investigated. Turbulent boundary layer flow is particularly interesting as well as challenging due to the presence of different interacting scales which are increasingly becoming significant as the flow inertial conditions keeps growing. Therefore, energy content of the coherent structures in outer layer becomes stronger and necessitates measurements in relatively large Reynolds number. Present control experiments in turbulent boundary layer can be split into two different work segments, where one is objected towards the data measurements in turbulent boundary layer over smooth surface with and without any external perturbation. Here, perturbation is applied in the form of wall normal blowing while keeping the magnitude of blowing very low compared to the free stream velocity. For the subsequent results reported here, magnitude of blowing ratio was varied between 0\%~6\%. In the first part of the present thesis e.g. 0.415×10e+3≤Reτ≤1.160×10e+3, measurements were performed at the Brandenburg University of Technology wind tunnel. Non-intrusive Laser Doppler Anemometry was applied to carry out a series of measurements on a zero pressure gradient flat plate turbulent boundary layer. Blowing ratio through the perforated surface was varied between 0.17\%~1.52\% of the free stream velocity. To a maximum of 50\% reduction in friction drag was achieved. For the measurements on the upper range of the stated Reynolds number, were conducted at the boundary layer wind tunnel. This boundary layer wind tunnel offers a spatially developed turbulent boundary layer over a flat plate within 2.2×10e+3≤Reτ≤5.5×10e+3 with an excellent spatial resolution. With the help of Stereo Particle Image Velocimetry technique, measurement of the velocity components were obtained covering entire boundary layer in streamwise wall normal plane. In addition, time resolved measurements were also obtained in spanwise and wall-normal plane in order to look into the morphology of turbulent structures immediately above the blowing area.}, language = {en} } @misc{RoddaHarlanderSavaroetal., author = {Rodda, Costanza and Harlander, Uwe and Savaro, C. and Campagne, A. and Calpe Linares, M. and Augier, P. and Sommeria, Joel and Valran, T. and Viboud, Samuel and Mordant, N.}, title = {Can Laboratory experiments help to explain the atmosphere and ocean's energetics?}, series = {Colaborative Research Center TRR 181, Energy transfers in Atmosphere and Oceans, 16th -
