Prandtl Number in Classical Hard-Sphere and One-Component Plasma Fluids [PDF]

Molecules, 2021
The Prandtl number is evaluated for the three-dimensional hard-sphere and one-component plasma fluids, from the dilute weakly coupled regime up to a dense strongly coupled regime near the fluid-solid phase transition.

Prandtl Number of Toroidal Plasmas

Journal of the Physical Society of Japan, 1993
Theory of the L -mode confinement in toroidal plasmas is developed. The Prandtl number, the ratio between the ion viscosity and the thermal conductivity is obtained for the anomalous transport process which is caused by the self-sustained turbulence in the toroidal plasma.

Turbulent-Prandtl-number models for liquid lead-bismuth in triangular rod bundles

He jishu, 2022
BackgroundIn order to accurately predict the heat transfer characteristics in the sub-channel of fuel assembly for the low Prandtl number fluid, it is necessary to select a suitable turbulent-Prandtl-number model.PurposeThis study aims at the ...

Proposal of a turbulent Prandtl number model for Reynolds-averaged Navier–Stokes approach on the modeling of turbulent heat transfer of low-Prandtl number liquid metal

Frontiers in Energy Research, 2022
Because of their high molecular heat conductivity, low-Prandtl number liquid metal is a promising candidate coolant for various designs of advanced nuclear systems such as liquid metal–cooled fast reactors and accelerator-driven sub-critical system (ADS).

Nonlinear stretched flow of a radiative MHD Prandtl fluid with entropy generation and mixed convection

Frontiers in Physics, 2023
This paper examines the analysis of entropy generation in the flow of an MHD Prandtl fluid over a nonlinear stretching sheet. Heat transfer is developed through a convectively heated sheet.

Thermal Convection for Large Prandtl Numbers [PDF]

Physical Review Letters, 2001
The Rayleigh-Benard theory by Grossmann and Lohse [J. Fluid Mech. 407, 27 (2000)] is extended towards very large Prandtl numbers Pr. The Nusselt number Nu is found here to be independent of Pr. However, for fixed Rayleigh numbers Ra> 10^{10} a maximum around Pr= 2 in the Nu(Pr)-dependence is predicted which is absent for lower Ra.

Hydromagnetic dynamos at the low Ekman and magnetic Prandtl numbers

Contributions to Geophysics and Geodesy, 2016
Hydromagnetic dynamos are numerically investigated at low Prandtl, Ekman and magnetic Prandtl numbers using the PARODY dynamo code. In all the investigated cases, the generated magnetic fields are dominantly-dipolar.
