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. In the laboratory context, the change can be modeled by an increase in total temperature accompanied by a reduction in the radial heat contrast.}, language = {en} } @misc{HallolYousryMerboldetal., author = {Hallol, Zeinab and Yousry, Mohamed and Merbold, Sebastian and Egbers, Christoph}, title = {Effect of High Reynolds Number on the Behaviour of Large and Very Large Scale Motions in Fully Developed Turbulent Pipe Flow}, series = {Fluid Dynamics}, volume = {57}, journal = {Fluid Dynamics}, number = {4}, issn = {0015-4628}, doi = {10.1134/S0015462822040048}, pages = {524 -- 537}, language = {en} } @inproceedings{Futterer, author = {Futterer, Birgit}, title = {3D-FG-Widerstandsmodellierung: Analyse von Diskretisierungsfehlern bei gitterunabh{\"a}ngiger Elektrodenpositionierung}, series = {19.

Numerical results show that these vortices propagate into the fluid bulk and generate an azimuthal mean flow. 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 - 18th Mar. 2021, Universit{\"a}t Hamburg, Center for Earth System Research and Sustainability (CEN)}, journal = {Colaborative Research Center TRR 181, Energy transfers in Atmosphere and Oceans, 16th - 18th Mar. 2021, Universit{\"a}t Hamburg, Center for Earth System Research and Sustainability (CEN)}, language = {en} } @phdthesis{MalteseMelettideOliveira, author = {Maltese Meletti de Oliveira, Gabriel}, title = {High-performance computing and laboratory experiments on strato-rotational instabilities}, address = {Cottbus}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:co1-opus4-54408}, pages = {155}, language = {en} } @misc{TravnikovEgbers, author = {Travnikov, Vadim and Egbers, Christoph}, title = {Linear stability analysis of the convective flow in a spherical gap with rotating inner surface}, series = {International Journal of Heat and Mass Transfer}, volume = {148}, journal = {International Journal of Heat and Mass Transfer}, issn = {0017-9310}, doi = {10.1016/j.ijheatmasstransfer.2019.119052}, pages = {10}, language = {en} } @misc{HallolYousryMerboldetal., author = {Hallol, Zeinab and Yousry, Mohamed and Merbold, Sebastian and Egbers, Christoph}, title = {Time-resolved PIV measurements in fully developed turbulent pipe flow}, series = {25th International Congress of Theoretical and Applied Mechanics Milan (Italy), 22-27 August 2021}, journal = {25th International Congress of Theoretical and Applied Mechanics Milan (Italy), 22-27 August 2021}, isbn = {978-83-65550-31-6}, pages = {1374 -- 1375}, language = {en} } @misc{SzaboZaussingerHaunetal., author = {Szabo, Peter and Zaussinger, Florian and Haun, Peter and Travnikov, Vadim and Meier, Martin and Egbers, Christoph}, title = {Complementary numerical and experimental study in the baroclinic annulus for the microgravity experiment AtmoFlow}, series = {EGU General Assembly 2020, EGU2020-20956, Online | 4-8 May 2020}, journal = {EGU General Assembly 2020, EGU2020-20956, Online | 4-8 May 2020}, doi = {10.5194/egusphere-egu2020-20956}, pages = {2}, language = {en} } @misc{ZaussingerCanfieldFroitzheimetal., author = {Zaussinger, Florian and Canfield, Peter and Froitzheim, Andreas and Travnikov, Vadim and Haun, Peter and Meier, Martin and Meyer, Antoine and Heintzmann, Pascal and Driebe, Thomas and Egbers, Christoph}, title = {AtmoFlow - Investigation of Atmospheric-Like Fluid Flows Under Microgravity Conditions}, series = {Microgravity Science and Technology : An International Journal for Microgravity and Space Exploration Related Research}, journal = {Microgravity Science and Technology : An International Journal for Microgravity and Space Exploration Related Research}, publisher = {Springer}, issn = {0938-0108}, doi = {10.1007/s12217-019-09717-7}, pages = {1 -- 19}, language = {en} } @misc{ZanounEgbersOerlietal., author = {Zanoun, El-Sayed and Egbers, Christoph and {\"O}rli, Ramis and Fiorini, Tommaso and Bellani, Gabriele and Talamelli, Alessandro}, title = {Experimental evaluation of the mean momentum and kinetic energy balance equations in turbulent pipe flows at high Reynolds number}, series = {Journal of Turbulence}, volume = {20}, journal = {Journal of Turbulence}, number = {5}, issn = {1468-5248}, doi = {10.1080/14685248.2019.1628968}, pages = {285 -- 299}, language = {en} }
