ABSTRACT

We carry out experimental investigation of flow and heat transfer in a film-cooling mixing unit as well as numerical calculation on the basis of a 3d equations of turbulent flow. The fact that flow structure is independent of cooler mass flow rate, i.e., Reynolds number, and is determined only by geometry is established. The turbulence and heat transfer depend on both geometry and Reynolds number.
