... and egress. Due to their spatial extent, none of these structures can exist in the 22.5 deg setup. The results show that for the investigated combination of turbine geometry and operating condition, the analysis of the downstream wheel space requires the detailed prediction of the unsteady flow phenomena...

.... Both heat transfer and skin friction modifications were found to strongly depend on the amplitude and wave speed of the unsteady flow perturbations. Over a wide range of disturbance parameters, skin friction modification was negligible, but a significant effect on heat transfer due to streaming...

... with the HPT stationary vanes. Downstream of the last HPT stage, the flow enters the intermediate turbine duct (ITD), where new unsteady components are generated, due to the interaction between the incoming flow and the struts supporting the ITD. This paper illustrates the differences between the unsteady flow...
