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

Scale of plume clustering in large-Prandtl-number convection [PDF]
, 2021 Clustering of plumes in turbulent Rayleigh-Bénard convection has been numerically observed in low-Prandtl-number fluids. In this framework, turbulent plumes undergo a phase-separation process leading to large-scale clusters and circulations, sometimes ...

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.

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.
