Abstract:

Experimental and analytical studies of film cooling isothermal effectiveness in subsonic flows are presented. In the experimental study, the shock tunnel was used and coolant flow was injected through slots and patterns of holes in both the streamwise and crosswise directions. The analysis indicates that the momentum ratio of the coolant to the mainflow is a critical parameter in the mixing process of the hot gas with the coolant gas. Further, a single dimension called the effective slot width is defined to determine the area of injection and the mixing surface.
