... Turbomachinery blading Design In an unshrouded high-pressure axial turbine, the tip leakage flow results in a reduction of the turbine efficiency and work output. The loss caused by the tip leakage flow accounts for as much as a third of the total aerodynamic loss of a turbine [ 1 ]. The tip...

... flow is also illustrated for understanding the origins and effects of losses in the turbine. Pressure ratios and efficiency at the speed combinations of the 80% to 100% inner and outer rotor design speeds are discussed to reveal the turbine characteristics at off-design conditions.
