Abstract: Algebraic closures for the turbulent scalar fluxes were evaluated for a discrete hole film cooling geometry using the results from a highfidelity large eddy simulation (LES). Several models for the turbulent scalar fluxes ...

Abstract: In film cooling flows, it is important to know the temperature distribution resulting from the interaction between a hot main flow and a cooler jet. However, current Reynolds-averaged Navier–Stokes (RANS) models yield poor ...
