Aerodynamic Performance and Leakage Flow in Turbine Cascades With Sweeping Jet Actuators

Shaowen Chen, Weihang Li, Pengcheng Yang, Yueqi Liu
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research Papers
J. Turbomach. June 2023, 145(6): 061015.

... on the aerodynamic performance and leakage flow is presented in a high-pressure turbine cascade. Comparing SJAs and hole-type steady jet actuators (HSJAs), the influence on the tip leakage flow and the loss characteristics at various incidences and injection frequencies are discussed in detail. The results indicate...
