Numerical Study on Vortex Structures and Loss Characteristics in a Transonic Turbine with Various Squealer Tips

Cavity width and height are two key geometric parameters of squealer tips, which could affect the control effect of squealer tips on tip leakage flow (TLF) of gas turbines. To explore the optimal values and the control mechanisms of cavity width and height, various cases with different cavity widths...
