Three Component Velocity Field Measurements in the Stagnation Region of a Film Cooled Turbine Vane

Abstract: The showerhead region of a film-cooled turbine vane in a gas turbine engine involves a complex interaction between mainstream flow and coolant jets. This flow field was studied using three component laser Doppler velocimeter measurements in a simulated turbine vane test facility. Measurements were focused around the stagnation row of holes. Low and high mainstream turbulence conditions were used. The spanwise orientation of the coolant jets, typical for showerhead coolant holes, had a dominating effect. Very h… Show more

“…In recent years, a great number of studies on film cooling have been carried out by both domestic and abroad scholars. Polanka studied the mixed characteristic of mainstream and jet in the blade leading edge of gas turbine by three-dimensional Laser Doppler Velocimetry (LDV) system [1]. Cutbirth studied the effect of inject holes of blade leading edge on pressure side and downstream of the jet [2].…”
