Abstract

Film cooling is used in turbine engines to avoid the critical heat loads on blade surfaces. The flowfield resulting from hot and cold gas interaction is rather complex and film-cooling effectiveness can be significantly reduced if intensive mixing occurs. The purpose of the present study is to investigate this interaction numerically, using Large Eddy Simulation. Special computational procedure coupling two different numerical codes is developed in order to tackle this problem. The performance of the coupling procedure is tested on steady and unsteady laminar flow problems. This methodology is then applied to the calculations of a jet in a crossflow as a model problem representing the flow interactions occurring during film-cooling.
