Zero Prandtl-number rotating magnetoconvection [PDF]
Physics of Fluids, 2017 We investigate instabilities and chaos near the onset of Rayleigh-Bénard convection of electrically conducting fluids with free-slip, perfectly electrically and thermally conducting boundary conditions in the presence of uniform rotation about the vertical axis and horizontal external magnetic field by considering zero Prandtl-number limit (Pr → 0 ...

Prandtl number effect on near wall temperature profile in high-Reynolds number channel flows
Nihon Kikai Gakkai ronbunshu, 2014 Prandtl number (Pr) effects on characteristics of the thermal boundary layer were investigated by means of Direct Numerical Simulations (DNS) in high-Reynolds number turbulent channel flows. The molecular Pr conditions were changed from 0.71 to 25.0, and

Velocity field in a high prandtl number liquid bridge
MATEC Web of Conferences, 2015 A numerical model is developed to investigate the velocity fields of high prandtl number liquid bridge with surface deformation under microgravity. The Navier-Stokes equations coupled with the energy conservation equation are solved on a staggered grid ...

Prandtl Number Effects on Mixed Convection Between Rotating Coaxial Disks
International Journal of Rotating Machinery, 1996 Prandtl number characterizes the competition of viscous and thermal diffusion effects and, therefore, is an influential factor in thermal-fluid flows. In the present study, the Prandtl number effects on non-isothermal flow and heat transfer between two ...

Dissipation in dynamos at low and high magnetic Prandtl numbers
, 2011 Using simulations of helically driven turbulence, it is shown that the ratio of kinetic to magnetic energy dissipation scales with the magnetic Prandtl number in power law fashion with an exponent of approximately 0.6. Over six orders of magnitude in the

A numerical simulation on high prandtl number liquid bridge
MATEC Web of Conferences, 2015 The free surface characteristics of high prandtl number liquid bridge with dynamic deformation have been investigated under microgravity based on the Navier-Stokes equations coupled with the energy conservation equation on a staggered grid.
