Spatio-Temporal Behavior of End-Wall Film Cooling of a Turbine Vane with Purge Flow Measured by Fast-Response Pressure-Sensitive Paint

Abstract The demand for high-efficiency, low-emission gas turbines has intensified with growing global energy consumption. In modern turbines, elevated inlet temperatures and uniform combustor-exit profiles expose the first-stage vane endwall to severe thermal loads. Complex vort...
