The effect of discrete delta-shaped tabs on the film cooling performance from a row of cylindrical holes in investigated. The holes are inclined at 35 deg along the streamwise direction. Three tab locations are investigated: (1) tabs placed along the upstream edge of the hole; (b) tab placed along the downstream edge of the hole; and (3) tabs placed along the lateral edges of the hole. Measurements were carried out in a low-speed wind tunnel using the transient liquid crystal technique. The mainstream velocity and free-stream turbulence intensity in the low speed wind tunnel are 8.5 m/s and 6
