Unsteady effects of vortex interaction on tip leakage vortex breakdown and its loss mechanism

Aerospace Science and Technology, 2018
Abstract In an unshrouded high-pressure turbine, tip leakage flow causes a loss of efficiency. The loss mechanisms of tip leakage flow were investigated mostly with steady uniform incoming conditions in previous studies. This paper investigated the unsteady aerodynamic performance of the tip leakage flow in a turbine stage by solving Unsteady ...

Effect of multiple DBD plasma actuators on the tip leakage flow structure and loss of a turbine cascade

International Journal of Heat and Fluid Flow, 2019
Abstract In this paper, the effects of multiple dielectric barrier discharge (DBD) plasma actuators on the leakage flow structures and loss conditions have been numerically studied in an axial turbine cascade. Kriging surrogate model is adopted to obtain the optimal cases.

Development of a tip leakage loss model for high-pressure turbines with squealer tips based on physics-driven and data-driven methods

Physics of Fluids
Tip leakage loss significantly influences aerodynamic performance of high-pressure turbines, with squealer tips serving as an effective control strategy. The development of a tip leakage loss model is crucial for evaluating and predicting turbine aerodynamic performance and guiding blade tip design.
