... with significant inlet flow incidences, potentially enabling turbine integration into rotating detonation engines. Initially, the requirements to ingest flow with high Mach numbers are identified and implemented in the vane geometry using endwall contouring, allowing a high level of turning with an extended...

...Zhengshuai Du; Le Cai; Yingjie Chen; Songtao Wang; Hongfei Tang; Jun Zeng The endwall contouring has proven to be an effective technique in controlling the impacts of secondary flow within turbomachinery. A baseline cascade with the original axisymmetric endwall (BASE) has been redesigned...

... groups involved in the design of endwall contours. The contours designed in this investigation were manufactured using the direct laser sintering rapid prototyping method and installed and tested in the low-speed, 1 1 2 -stage turbine at the CSIR’s test turbine facility (TTF) in Pretoria, South Africa...
