Asymptotic Behaviour of Galactic Small-scale Dynamos at Modest Magnetic Prandtl Number

open access: yesThe Astrophysical Journal Letters
Magnetic fields are critical at many scales to galactic dynamics and structure, including multiphase pressure balance, dust processing, and star formation. Dynamo action determines their dynamical structure and strength.

Turbulent Prandtl number analysis of helium-xenon gas flow and heat transfer in the parallel channel

open access: yesInternational Journal of Advanced Nuclear Reactor Design and Technology
The helium-xenon gas mixtures (15-40 g/mol) are used in various designs of small gas-cooled nuclear reactor systems with Prandtl number (Pr) from 0.2 to 0.3.

Development of a test task for coupled neutronic and thermal-hydraulic analysis of LFR fuel cell

open access: yesNuclear Engineering and Technology
In the absence of operational experience with Generation IV reactors and limited experimental data, developing test tasks is crucial for ensuring the safety and reliability of novel reactor designs.

A collaborative effort towards the accurate prediction of turbulent flow and heat transfer in low-Prandtl number fluids

open access: yes, 2019
This article reports the experimental and DNS database that has been generated, within the framework of the EU SESAME and MYRTE projects, for various low-Prandtl flow configurations in different flow regimes. This includes three experiments: confined and

THE INTERACTION BETWEEN RADIATION AND TURBULENT NATURAL CONVECTION IN SQUARE AND RECTANGULAR ENCLOSURES [PDF]

open access: yes, 2013
Heat transfer by natural convection inside enclosed spaces with radiation interaction is of practical interest in many engineering applications, such as design of buildings for thermal comfort, nuclear reactors, solar collectors, and the cooling of ...

Behaviour of turbulent Prandtl/Schmidt number in compressible mixing layer

open access: yes, 2015
The behaviour of turbulent Prandtl/Schmidt number is explored through the model-free simulation results. It has been observed that compressibility affects the Reynolds scalar flux vectors. Reduced peak values are also observed for compressible convective

Comparative Analysis Of Different Turbulent Mixing Length Models For Low Prandtl Number Fluids

open access: yes, 2015
The present article studies some models of turbulent Prandtl number for low and very low-Prandtl-number fluids. It was investigated model of Cebeci, two models of Kays, and model of Wassel and Catton.

MEAN AND TURBULENT THERMAL FIELDS DUE TO FILM COOLING VIA AN EDDY HEAT DIFFUSIVITY CLOSURE

open access: yesTASK Quarterly, 2006
The two-equation level of turbulent heat flux modelling is considered for application in film cooling instead of the turbulent Prandtl number concept.

Role of Turbulent Prandtl Number on Heat Flux at Hypersonic Mach Numbers

open access: yes, 2005
A new turbulence model suited for calculating the turbulent Prandtl number as part of the solution is presented. The model is based on a set of two equations: one governing the variance of the enthalpy and the other governing its dissipation rate.
