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

Bifurcation and chaos in zero-Prandtl-number convection [PDF]
EPL (Europhysics Letters), 2009 We present the detailed bifurcation structure and associated flow patterns near the onset of zero Prandtl number Rayleigh Bénard convection. We employ both direct numerical simulation and a low-dimensional model ensuring qualitative agreement between the two.

Turbulent passive scalar field of a small prandtl number [PDF]
, 1986 The statistical-mechanics theory of the passive scalar field convected by turbulence, developed in an earlier paper [Phys. Fluids 28, 1299 (1985)], is extended to the case of a small molecular Prandtl number.

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.
