Turbulent Prandtl Number and its Use in Prediction of Heat Transfer Coefficient for Liquids [PDF]

open access: yesمجلة النهرين للعلوم الهندسية, 2007
A theoretical study is performed to determine the turbulent Prandtl number (Prt ) for liquids of wide range of molecular Prandtl number (Pr=1 to 600) under turbulent flow conditions of Reynolds number range 10000- 100000 by analysis of experimental ...

The effect of Prandtl number on turbulent sheared thermal convection [PDF]

open access: yes, 2021
In turbulent wall sheared thermal convection, there are three different flow regimes, depending on the relative relevance of thermal forcing and wall shear.

Turbulent Prandtl number from isotropically forced turbulence

open access: yes, 2022
Turbulent motions enhance the diffusion of large-scale flows and temperature gradients. Such diffusion is often parameterized by coefficients of turbulent viscosity ( $\nu _{t}$ ) and turbulent thermal diffusivity ( $\chi _{t}$ ) that are analogous to ...

Two-dimensional magnetohydrodynamic turbulence in the small magnetic Prandtl number limit [PDF]

open access: yes, 2012
In this paper we introduce a new method for computations of two-dimensional magnetohydrodynamic (MHD) turbulence at low magnetic Prandtl number $\Pra=\nu/\eta$.

Temperature statistics in turbulent Rayleigh–Bénard convection with a Prandtl number of Pr = 12.3

open access: yesAIP Advances, 2022
The transport of plumes in turbulent convective systems must be understood to study the mantle and various industrial applications. We measured the probability density function P(T) of the temperature at various radial and vertical positions in the bulk ...
