This project aims to guarantee the film cooling of turbine stators for all operating conditions and will as well assess the performance characteristics of the turbine. Experimental investigations at the Hot-Acoustic-Testrig (HAT) and TU-Pulse-Testrig will be carried out to identify the impact of the moving stagnation point line on the cooling concept and characteristics of turbines. Numerical studies will help to better understand the unsteady mixing processes of the cooling flow with the hot main flow and to derive specific design criteria for turbines with unsteady boundary conditions.

本项目旨在保证涡轮机定子在所有运行条件下的薄膜冷却，并评估涡轮机的性能特征。将在热声测试（HAT）和TU-Pulse-Testrig进行实验研究，以确定移动驻点线对涡轮机冷却概念和特性的影响。数值研究将有助于更好地理解冷却流与热主流的非定常混合过程，并导出具有非定常边界条件的涡轮机的具体设计准则。
