Abstract

Abstract

The overall cooling effectiveness of the inclined multihole plates was investigated through approximate simulation experiments.The plates had five different geometry configurations.The experimental results indicated that the convective heat transfer coefficient in the cooling hole,the adiabatic film effectiveness and geometrical configuration were the critical factors for the overall cooling effectiveness.The investigation plays an important role in designing the inclined multihole wall and selecting the geometry of these cooling configuration.
