High Reynolds number Taylor-Couette turbulence
Siegfried Grossmann, Detlef Lohse, Chao Sun
Taylor-Couette flow -- the flow between two coaxial co- or counter-rotating cylinders -- is one of the paradigmatic systems in physics of fluids. The (dimensionless) control parame…
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…
Salinity transfer in bounded double diffusive convection
Yantao Yang, Erwin P. van der Poel, Rodolfo Ostilla-Mónico +4
The double diffusive convection between two parallel plates is numerically studied for a series of parameters. The flow is driven by the salinity difference and stabilized by the t…
Logarithmic mean temperature profiles and their connection to plume emissions in turbulent Rayleigh-Bénard convection
Erwin P. van der Poel, Rodolfo Ostilla-Mónico, Roberto Verzicco +2
Two-dimensional simulations of Rayleigh-Bénard convection at show that vertical logarithmic mean temperature profiles can be observed in regions of the bounda…
The near-wall region of highly turbulent Taylor-Couette flow
Rodolfo Ostilla-Mónico, Roberto Verzicco, Siegfried Grossmann +1
Direct numerical simulations of the Taylor-Couette (TC) problem, the flow between two coaxial and independently rotating cylinders, have been performed. The study focuses on TC flo…
Exploring the phase diagram of fully turbulent Taylor-Couette flow
Rodolfo Ostilla Mónico, Erwin P. van der Poel, Roberto Verzicco +2
Direct numerical simulations of Taylor-Couette flow (TC). Shear Reynolds numbers of up to , corresponding to Taylor numbers of , were reached. Effec…
