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} } @inproceedings{FruehSzaboSeeligetal., author = {Fr{\"u}h, Wolf-Gerrit and Szabo, Peter and Seelig, Torsten and Hoff, Michael and Egbers, Christoph}, title = {Spectral Features of the transition to structural vacillation in the baroclinic annulus}, 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 = {36 -- 37}, language = {en} } @inproceedings{HarlanderSeeligGellertetal., author = {Harlander, Uwe and Seelig, Torsten and Gellert, Marcus and Viazzo, Stephane and Randriamampianina, Anthony and Egbers, Christoph and R{\"u}diger, G{\"u}nther}, title = {Stratorotational instability in a thermally stratified taylor-couette flow}, series = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, booktitle = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{HarlanderSeeligGellertetal., author = {Harlander, Uwe and Seelig, Torsten and Gellert, Marcus and Viazzo, Stephane and Randriamampianina, Anthony and Egbers, Christoph and R{\"u}diger, G{\"u}nther}, title = {Stratorotational instability: nonlinear aspects at higher reynolds numbers}, series = {EUROMECH Colloquium 567, Turbulent mixing in stratified flows 22-25 March 2015, DAMTP, Centre for Mathematical Sciences, Cambridge}, booktitle = {EUROMECH Colloquium 567, Turbulent mixing in stratified flows 22-25 March 2015, DAMTP, Centre for Mathematical Sciences, Cambridge}, pages = {1}, language = {en} } @inproceedings{HarlanderSeeligStapelfeldetal., author = {Harlander, Uwe and Seelig, Torsten and Stapelfeld, Ludwig and Gellert, Marcus and Viazzo, Stephane and Randriamampianina, Anthony and Egbers, Christoph and R{\"u}diger, G{\"u}nther}, title = {Stratorotational Instability: nonlinear aspects at higher Reynolds numbers}, 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 = {132 -- 133}, 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{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} }
