Film cooling can continuously cover a layer of low-temperature gas film on the surface hot-end components, thereby achieving effect isolating high-temperature gas, and achieve temperature drop 600 K. As an advanced efficient technique, plays crucial role in process turbine power efficiency increase, with key factor influencing its performance being configuration arrangement holes. This paper summarizes design hole configurations discusses potential directions for enhancing performance. Through analysis, optimization is mainly approached from two aspects: first, optimizing configuration, which includes study shaped holes, cylindrical holes using auxiliary structures, forming “reverse kidney-shaped vortex” structure by single combined hole; second, to more uniform distribution film. Future development trends are primarily reflected following designing new, easily manufacturable, high-efficiency further expanding their stable operating range important direction. It essential validate reverse heat transfer method, assess applicable range, and, when experimental conditions exceed use related theories correct predictive overcoming bottleneck prediction. critical develop guideline that suitable various types components differences at thermal end, fill gap future technologies. aims provide new ideas optimal system improve turbines.
