Abstract: Previous studies have indicated a potential for improving the performance of a turbine center frame (TCF) duct by optimizing the clocking position between the high-pressure turbine (HPT) vanes and TCF struts. To assess the ...

Abstract: This paper presents the unsteady flow interactions between an engine-representative high-pressure turbine (HPT) and low-pressure turbine (LPT) stage, connected by a turbine center frame (TCF) duct with nonturning struts. ...

Abstract: This paper presents the experimental and numerical evaluation and comparison of the different flow fields downstream of a turbine center frame duct and a low-pressure turbine (LPT) stage, generated by varying the inlet ...
