... the predictability of the RANS (Reynolds-averaged Navier Stokes) approach, we implemented the dynamic modeling for turbulent Schmidt Sc t and Prandtl Pr t numbers. In this paper, the capability of the RANS analysis with dynamic Sc t modeling is assessed with several experimental data obtained by using the MISTRA...

...% of those in the corresponding forced convection case. The heat transfer performance of such ‘mixed’ convection flows is investigated here using a range of refined Reynolds-Averaged-Navier-Stokes (RANS) turbulence models. While all belong to the broad class of Eddy Viscosity Models (EVMs), the various RANS...
