Influence of Relative Position of the Initial Region of Double-Row Perforation of the Turbine Vane Suction Side on the Film Cooling Effectiveness in Conditions of Inlet Flow Irregularity
摘要
Abstract
The paper presents the results of investigation of the film cooling formation features in the double-row perforation on the turbine vane suction side in conditions of the inlet total pressure field irregularity. It is shown, that transition to the corridor arrangement of perforation on the turbine vane suction side has a positive impact on vane temperature condition at the inlet total pressure gradient region.
