An Experimental investigation was performed on turbulent channel flow with injection through an inclined slit. The wall static pressure, cooling effectiveness, velocity profile and turbulent intensity were measured behind the slit. The tests were conducted for three inclined angles for 30°, 60° and 90° at the main stream velocity 10m/s for three dimensionless injection flow rations of 0.067,0.133 and 0.200. It is found that the cooling effectiveness increases with decreasing the inclined angle, and increases with increasing the dimensionless injection flow ratio
