Abstract:
Various papers and research works regarding film cooling performance were studied. Parameters, conditions and geometry factors that affect the film cooling effectiveness were analyzed. The objective was to see how modifications such as dual row of anti-vortex hole configuration, and diffuser shaped anti-vortex configuration affected the overall cooling effectiveness, when compared to the performance for the conventional single row of cylindrical holes. The basis of comparison was film cooling applied over a flat plate, and the resulting cooling effectiveness produced. The numerical study was executed on CFX package. Validation of the simulation technique was attempted with reference to the experimental works of A.K Sinha in “Film Cooling Effectiveness Downstream of a Single Row of Holes with Variable Density Ratio”.
