Influence of Aspect Ratio on the Onset of Thermocapillary Oscillatory Convection in a Floating Half Zone of Large Prandtl Number Fluid

, 2003
The onset of oscillatory thermocapillary convection in a floating half zone of 10 cst silicon oil (Prandtl number 105.6) is studied by the three-dimensional and unsteady numerical simulation in microgravity environment (g=10~{-4}_{gearth}).

Numerical Simulation of Turbulent Channel Flow at Low Prandtl Number [PDF]

, 2016
Liquid metals are primary coolants in Generation IV nuclear reactors. For low Prandtl\ud fluids, such as liquid metals, classical Reynolds analogy of using turbulent Prandtl number\ud close to unity doesnt predict heat transfer characteristics ...

Double-Diffusive Convection at Low Prandtl Number

, 2018
This work reviews present knowledge of double-diffusive convection at low Prandtl number obtained using direct numerical simulations, in both the fingering regime and the oscillatory regime. Particular emphasis is given to modeling the induced turbulent

Numerical Study of Convective Flow of Casson Fluid Through an Infinite Vertical Plate with Induced Magnetic Field

East European Journal of Physics
The present objective is to numerically analyze the induced magnetic field (IMF) effect of an unsteady MHD flow of Casson fluid through two infinite vertical plates. The effect of radiative heat has been scrutinized. Governing non-dimensional PDEs of the

Variable Turbulent Prandtl Number Model for Shock/Boundary-Layer Interaction

, 2018
Interaction of shock waves with turbulent boundary layers can enhance the surface heat flux dramatically. Reynolds-averaged Navier-Stokes simulations based on a constant turbulent Prandtl number often give grossly erroneous heat transfer predictions in ...
