<p>This article presents experimental investigations of film heating heat transfer over wedge surfaces with apex angles of 30° and 70°. The performance of these test sections is evaluated based on the heat transfer coefficient ratio (HCR). The HCR data are reported along the hole centerline and across the cross-stream direction for different blowing ratios (M). Additionally, span-wise-averaged HCR values along the stream-wise direction are presented. The injection angle was maintained at 55° relative to the wedge surface, and the blowing ratio was varied from 0.3 to 2.5 for each test section. The experimental setup and data reduction procedures were validated against available literature for flat plates and wedge surfaces. Temperatures of the fluid streams and the test section surface were measured at steady-state conditions using calibrated K-type thermocouples and a calibrated infrared (IR) thermal camera, respectively. The heat transfer coefficient ratio decreases along the stream-wise direction due to mixing of the secondary fluid with the primary flow. At far downstream locations, the ratio approaches unity, corresponding to the heat transfer coefficient without film injection. The HCR increases with increasing blowing ratio due to stronger interaction between the mainstream and jet fluid. Maximum HCR values are observed along the hole centerline and decrease on either side of the hole, owing to the spreading of the secondary fluid in the cross-stream direction. The HCR also decreases with increasing apex angle of the wedge surface. Overall, the characteristics of the HCR data are similar to those observed for flat plate surfaces across all blowing ratios.</p>
