The SquAd derivation: A Square Additive approach to the turbulent Prandtl number [version 3; peer review: 1 approved, 3 approved with reservations, 1 not approved] [PDF]
Open Research Europe, 2023 Liquid metals have been chosen as primary coolant of innovative nuclear systems under current development. They present a very high thermal conductivity and hence a very low molecular Prandtl number.

Method of calculation of turbulent Prandtl number for the SST turbulence model
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 We present a new model for turbulent Prandtl number that provides an improvement of prediction capabilities of the SST turbulence model in application to wall heat transfer problems. The model developed gives an explicit expression for the local value of

THE TURBULENT MAGNETIC PRANDTL NUMBER OF MHD TURBULENCE IN DISKS [PDF]
The Astrophysical Journal, 2009 The magnetic Prandtl number Pr_M is the ratio of viscosity to resistivity. In astrophysical disks the diffusion of angular momentum (viscosity) and magnetic fields (resistivity) are controlled by turbulence. Phenomenological models of the evolution of large scale poloidal magnetic fields in disks suggest that the turbulent magnetic Prandtl number Pr_{M,

A New Anisotropic Four-Parameter Turbulence Model for Low Prandtl Number Fluids
Fluids, 2021 Due to their interesting thermal properties, liquid metals are widely studied for heat transfer applications where large heat fluxes occur. In the framework of the Reynolds-Averaged Navier–Stokes (RANS) approach, the Simple Gradient Diffusion Hypothesis (

Two-loop calculation of the turbulent Prandtl number [PDF]
Physical Review E, 2005 The turbulent Prandtl number has been calculated in the two-loop approximation of the $\eps$ expansion of the stochastic theory of turbulence. The strikingly small value obtained for the two-loop correction explains the good agreement of the earlier one-loop result with the experiment.
