On multiple stable states in Taylor-Couette flow with realistic end-wall boundary conditions
Marvin Kriening, Zhongzhi Yao, Mohammad S. Emran +3
We investigate Taylor-Couette flow with realistic no-slip boundary conditions at all surfaces through direct numerical simulations (DNS) and theoretical analysis. Imposing physical…
Mean Temperature Profiles in Turbulent Thermal Convection
Olga Shishkina, Susanne Horn, Mohammad S. Emran +1
To predict the mean temperature profiles in turbulent thermal convection, the thermal boundary layer (BL) equation including the effects of fluctuations has to be solved. In Shishk…
Scaling relations in large-Prandtl-number natural thermal convection
Olga Shishkina, Mohammad S. Emran, Siegfried Grossmann +1
In this study we follow Grossmann and Lohse, Phys. Rev. Lett. 86 (2001), who derived various scalings regimes for the dependence of the Nusselt number and the Reynolds number…
Large-scale mean patterns in turbulent convection
Mohammad S. Emran, Jörg Schumacher
Large-scale patterns, which are well-known from the spiral defect chaos regime of thermal convection at Rayleigh numbers , continue to exist in three-dimensional numeric…
Resolving the fine-scale structure in turbulent Rayleigh-Benard convection
Janet D. Scheel, Mohammad S. Emran, Joerg Schumacher
We present high-resolution direct numerical simulation studies of turbulent Rayleigh-Benard convection in a closed cylindrical cell with an aspect ratio of one. The focus of our an…
Boundary layer evolution in turbulent Rayleigh-Benard convection
Herwig Zilken, Mohammad S. Emran, Joerg Schumacher
We present a fluid dynamics video which illustrates the dynamics of the velocity field in the boundary layer in a turbulent Rayleigh-Benard convection flow. The data are obtained f…
