Interference Effect of Shock Wave on Tip Leakage Vortex in a Transonic Variable Nozzle Turbine
International Journal of Turbomachinery, Propulsion and PowerThe tip leakage flow at both sides of the nozzle vane is an important factor for the reduction in turbine aerothermal performance. A strong shock wave is generated at the trailing edge of the nozzle vane under transonic condition, which can interfere ...

Energies, 2022 To operate, radial turbines used in turbochargers require a minimum tip gap between the rotor blades and the stationary wall casing (shroud). This gap generates leakage flow driven by the pressure difference between the pressure and suction side. The tip

Tip Leakage Losses in a Linear Turbine Cascade [PDF]
Journal of Turbomachinery, 1990 An investigation of tip leakage flow and its effects on loss production was performed on a large-scale linear turbine cascade having a tip gap measuring 2.1 percent of the blade height. The flow exiting the tip gap was measured to determine the losses incurred within the tip gap and the secondary kinetic energy due to tip leakage.

Control of Tip Leakage in a High-Pressure Turbine Cascade Using Tip Blowing [PDF]
Journal of Turbomachinery, 2016 Blowing from the tip of a turbine blade was studied experimentally to determine if total pressure loss could be reduced. Experiments were done with a linear cascade in a low-speed wind tunnel. Total pressure drop through the blade row and secondary velocity fields in the passage between two blades were measured.

Tip Leakage Flow in a Linear Turbine Cascade [PDF]
Journal of Turbomachinery, 1988 An experimental and analytical study of flow in the tip clearance gap of a linear turbine rotor blade cascade has been performed. Measurements of wall static pressures and flow velocities are used to verify a flow model involving a vena contracta, near the tip gap entrance, followed by flow mixing to fill the gap. A frequently referenced potential flow
