Influence of Mach Number of Main Flow on Film Cooling Characteristics under Supersonic Condition

The flow and heat transfer characteristics of a film jet inclined to different supersonic situations with varying Mach number the main were numerically investigated. In situations, complicated waves are generated by obstacle jet. this work, extra pressure is exerted onto jet, causing better attachment wall. strengthening decreases mixing between cooling. We observed multi-interfacial layered structures caused under effect shock waves. At interfaces waves, additional on towards increases as contributes increased adhesion gas film, which causes cooling enhancement condition. vicinity hole exit, local low region formed influence flow. An aerodynamic convergent–divergent state was in hole, devastating congestion further enhancing effect.
