Effect of blockages on film effectiveness on the pressure surface of a turbine blade

An experimental and numerical study was conducted on fanshaped holes on the pressure surface of a high-pressure turbine blade. Blockages in these film holes can arise through dirt accumulation as well as erosion of the thermal barrier coatings. The objective was to study the effects of partial block...
