Cooling and Performance of a Turbine under periodically unsteady inflow conditions (B05)

该项目旨在保证涡轮定子在所有运行条件下的气膜冷却，并将评估涡轮的性能特性。将在热声试验台(HAT)和脉冲试验台(TU-Pulse-Testrig)上进行实验研究，以确定运动驻点线对涡轮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，并推导出具有非定常边界条件的水轮机的具体设计准则。

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.
