An experimental method for squealer tip flow field considering relative casing motion
Chinese Journal of Aeronautics, 2020 Abstract Squealer tip is widely used in turbines to reduce tip leakage loss. In typical turbine environment, the squealer tip leakage flow is affected by multiple factors such as the relative casing motion and the wide range of variable incidence angles.
