航空エンジン用低圧タービンにおける形状損失に関する研究

（流入 wake の形状変化と混合損失との関係）

抄録

Turbines are used in aeroengines and generators, and turbine blades generate power. In actual machine, the turbine is exposed to a harsh environment because the mainstream and the wake, which is generated at the trailing edge of the upstream blade inflow into the domain. The influence owing to the wake inflowing has been studied for a long time. And we have revealed that the wake inflowing make the separation bubble short. Although it is important to study how the wake inflowing affect the flow field, it has never been understood clearly. The reason is that the wake inflowing not only affect the shape loss but accumulate as the loss at the flow domain. We need to investigate the wake mixing loss isolation from whole cascade loss. In this study, we separate wake mixing loss from cascade loss by using Denton Loss and new method. Besides, we study the relationship between the loss and the shape of the domain by estimating the wake deformation.
