Abstract: This study focuses on the thermal impact of the clocking position of the high-pressure turbine (HPT) vanes with respect to the turbine center frame (TCF) struts and the thermal impact of the HPT outlet swirl. The TCF is a ...

Abstract: It was shown in the previous study that the aft purge flows from the last stage of the high-pressure turbine (HPT) have a significant film cooling potential in the downstream turbine center frame (TCF) (Jagerhofer et al., ...

Abstract: Abstract. This paper investigates heat transfer in a turbine center frame (TCF), a transition duct that guides the flow from the high-pressure to the low-pressure turbine. Experimental results were acquired in a high-speed ...

Abstract: The imperative improvement in the efficiency of turbofan engines is commonly facilitated by increasing the turbine inlet temperature (TIT). This development has reached a point where also components downstream of the ...

Abstract: Abstract. This article investigates heat transfer in a turbine center frame (TCF), focusing on the effects of combustor temperature non-uniformities, more commonly referred to as hot streaks (HSs). It is a continuation of ...

Abstract: The turbine center frame (TCF) is an inherent component of turbofan aircraft engines and is used for connecting the high-pressure turbine (HPT) to the low-pressure turbine (LPT). Its position immediately downstream of the ...
