Turbulent Prandtl Number and its Use in Prediction of Heat Transfer Coefficient for Liquids
مجلة 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 ...

, 1993 It is shown that turbulent Prandtl numbers for turbulent boundary layer and jet flows correlate well if compared on the basis of eddy diffusivity. Experimental data for liquid sodium (Pr= 0.0058) lead to a universal expression relating turbulent Prandtl ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Machine learning offers a flexible route to constitutive modeling, with two emergent questions for geoscience applications: what level of thermodynamic constraint should be embedded in the network architecture, and how should predictive uncertainty be quantified when extrapolating from laboratory to field conditions? We address both challenges

Bound on vertical heat transport at large Prandtl number
, 2007 We prove a new upper bound on the vertical heat transport in Rayleigh-Bénard con-vection at large (but finite) Prandtl number that agrees with the (optimal) Ra 1 3 bound (modulo logarithmic correction) on vertical heat transport for the infinite Prandtl ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.Abstract Boundary layer turbulence and vertical mixing exert great control over the structure and evolution of tropical cyclones (TCs). However, scaling and parameterizing them remains challenging due to their inherent complexity and limited observations.

Infinite Prandtl number limit of Rayleigh‐Bénard convection
, 2004 We rigorously justify the infinite Prandtl number model of convection as the limit of the Boussinesq approximation to the Rayleigh-Bénard convection as the Prandtl number approaches infinity. This is a singular limit problem involving an initial layer. ©
