Abstract

Measurements of mean velocity and turbulence intensity are presented for the mixing region of a film cooling situation in which the coolant is laterally injected. Measurements are performed using triplesensor ancmomctry so that all three velocity components are documented. Flow with one row of film cooling holes inclined 35° to the surface, with lateral injection (Φ = 90°), is documented. The frecstream turbulence intensity level is 12%. and coolant-to-mainstream velocity ratios are 0.5 and 1.0 (the density ratio is unity). General flow field characteristics ore discussed and compared. Additional comparisons are made with similar measurements in a flow in which the injection is streamwise (Φ = 0°).
