Conjugate Heat Transfer Simulation of Overall Cooling Performance for Cratered Film Cooling Holes
Film cooling is widely applied as an effective way to maintain the turbine blade temperature at an acceptable level. The present paper investigates the overall cooling effectiveness and flow structure by performing conjugate heat transfer simulations for the flat-plate baseline cylindrical and three cratered film-cooling holes. The flow and heat transfer in the fluid domain is obtained using the Shear Stress Transport turbulence model, and the solid conductivity is considered by solving thedoi:10.3390/machines10050395 fatcat:4p3pqsonqrctpp3amqn4qur5wu
