Abstract

Effects of the inclination angles on the mixing process and the film cooling is presented for a rectangular two-dimensional (2-D) domain. For this purpose five different inclination angles are taken into account. Computational solution is performed by using Re-Normalized k-epsilon (RNG) turbulence model with near-wall treatment. Additional transport equations for different species to analyze the mixing process of air crossflow and CO2 cooling jet are also solved. Effects of the blowing ratios are also investigated by taking two different blowing ratios, M=0.15 and 1.20.
