A6 Transition in rotating turbulent Rayleigh-Bènard convection

Prof. Dr. Eberhard Bodenschatz, Prof. Dr. Andreas Tilgner, Prof. Dr. Claus Wagner

Here we investigate quantitatively in a combined experimental and numerical approach the role of rotation on large-scale flow structure formation, heat transport, and the boundary layer dynamics. By using compressed gasses up to 19 bars we shall have access to the very high Rayleigh numbers 1010 < Ra < 1015. We shall compare the experiments with high resolution Direct Numerical Simulations and Large-Eddy Simulations. The simulations will take into account the rotation rates as well as temperature-and pressure-dependent properties of the fluids. This project will develop experimentally verified numerical methods applicable to astrophysical situations.
