Reacting and non-reacting flow simulation for film cooling in 2-D supersonic flows

Abstract

A computational fluid dynamics (CFD) model is developed for the analysis of reacting and non-reacting film cooling supersonic flows. The present study demonstrates the effectiveness of using an extended twoequation turbulence model with compressibility corrections for supersonic shear-layer simulations. An efficient finite-rate chemistry solution method is employed for effective simulation of stiff chemistry systems. Two-dimensional supersonic film cooling test cases with and without chemical reaction are investigated for the validation of the present model. The underlying fluid dynamics solver is a predictor plus multi-comector pressure based Navier-Stokes flow solver.
