Film Cooling Simulation and Control
要約
Numerical simulation strategies for film cooling flows ranging from time-averaged simulations based on Reynolds-averaged equations to fully unsteady simulations are presented and reviewed. Simulation results are presented for both cylindrical and shaped holes with the key emphasis in this paper on the accuracy of the averaged results and on the film-cooling flow physics. It is shown that the Reynolds-averaged equations with turbulence models need anisotropy and realizability corrections to provide correct predictions for the cooling effectiveness. Spatially filtered unsteady simulations (called large-eddy simulations) appear to provide the needed quantitative accuracy and the rich flow physics representing such flows.
