Title

An Inverse Bem/Ga Based Approach For Retrieval Of Multi-Dimensional Heat Transfer Coefficients Within Film Cooling Holes/Slots

Abstract

An inverse methodology is developed as a means of determining heat transfer coefficients in film cooling holes/slots. Thermal conditions are over-specified at exposed surfaces amenable to measurement, while the temperature and surface heat flux are unknown at the film cooling slot walls. The latter are determined in an iterative manner by solving an inverse problem whose objective is to adjust the film-cooling slot wall temperatures and heat fluxes until the temperature and heat flux at the measurement surfaces are matched in an overall heat conduction solution. The heat conduction problem is solved using boundary elements, and the inverse problem is solved using a genetic algorithm.
