... exacerbating the backflow of the tip leakage flow, which occurred at middle and rear of the tip clearance and had not evolved into tip vortex. Email: zhaojy@sdju.edu.cn Email: wywu@shmtu.edu.cn 1 Corresponding author. Email: zhongjj@shmtu.edu.cn Email: zengly@sdju.edu.cn 27 03 2024...

... 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...

... and Atkins [ 3 ]. Squealer tips featuring various wall openings were examined by Vass and Arts [ 4 ]. The authors stated that the full perimeter squealer featured the lowest kinetic energy losses, compared to the partial suction and pressure-side squealer. Simple and optimized squealer tips leakage flow has...

...Sergen Sakaoglu; Harika S. Kahveci The pressure difference between suction and pressure sides of a turbine blade leads to tip leakage flow, which adversely affects the first-stage high-pressure (HP) turbine blade tip aerodynamics. In modern gas turbines, HP turbine blade tips are exposed to extreme...

... allowed a spatial assignment of the origin of the tip leakage flow and the downstream developing vortex. In addition, the tip clearance vortex could be resolved and identified successfully as the most dominant turbulence generating effect in the near endwall region at this high loading operating point...

...Bruno Pereiras; Francisco Castro; Abdelatif el Marjani; Miguel A. Rodríguez Turbines for wave energy conversion have a special feature to be taken into account in the study of the tip leakage flow: These turbines are self-rectifying, which work inside a cyclically bidirectional flow alternatively...

... of the tip leakage flow is investigated in the compressor without control. The simulation shows an increase in the interaction between the tip leakage flow and the main flow when the mass flow is reduced, a phenomenon responsible for the development of a large flow blockage region at the rotor leading edge...
