Abstract: The practical performance, both the efficiency and durability, of a high-pressure (HP) turbine depends on many interrelated factors, including both the steady and unsteady aerodynamics and the ...

Abstract: In a gas turbine engine the blade tips of the high-pressure turbine are exposed to high levels of convective heat transfer, because of the so-called tip-leakage phenomenon. The blade-lift ...

Abstract: In this paper, high and low speed tip flows are investigated for a high-pressure turbine blade. Previous experimental data are used to validate a computational fluid dynamics (CFD) code, which ...
