To compare with great deal of experimental data , the results show the improved method could be used as a generalized design methodology of film cooling for turbine blade . predictions of span - wise averaged effectiveness are made with a two - dimensional boundary layer code using the low reynolds number k - two - equation turbulent model 研究并发展了用低雷诺数k -紊流模型为基础的气膜冷却计算方法,将前人针对平板提出的掺混模型推广应用于涡轮叶片型面,得到了与实验数据符合良好的结果。
