Aerodynamic loss reduction in a vane cascade with leading edge fillet and upstream endwall film cooling

Arnachellan, Keenesh (University of Pretoria, 2017)

Secondary flow structures account for nearly 50% of aerodynamic losses experienced in the turbine blade passages. The adverse effects of these vortex structures transport the hot mainstream fluid towards the endwall blade ...
Effects of upstream endwall film cooling on a vane cascade flowfield

Mahmood, Gazi I.; Arnachellan, Keenesh (American Institute of Aeronautics and Astronautics Inc., 2018-03)

The effects of film cooling on the endwall region flow and aerodynamic losses are investigated experimentally as the film flow is delivered from the slots in the endwall upstream of a linear vane cascade. Four slots inclined ...
