axial gas turbine blade cooling with impingement/film-cooling

. and Mass Transport 08 May 2008, Lund, Sweden Axial gas turbine blade cooling With Impingement/Film-Cooling Adrian Dahlquist Dept. of Energy Sciences, Faculty of., “free stream” direction (x,y,z) 2 Introduction: In the gas turbine hot air enters the nozzle at a high speed and. used together whit different cooling techniques. Also the cooling efficiency and turbine blade melting temperature are shown. [5] 3 • Impingement cooling is when a concentrated airflow is impinging on the inner surface of the blade.
