Heat Transfer and Flow on the Squealer Tip of a Gas Turbine Blade [PDF]
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2000 Experimental investigations are performed to measure the detailed heat transfer coefficient and static pressure distributions on the squealer tip of a gas turbine blade in a five-bladed stationary linear cascade. The blade is a 2-dimensional model of a modern first stage gas turbine rotor blade with a blade tip profile of a GE-E3 aircraft gas turbine ...
