Cooling Flow Prediction for Fully Impingement Cooled Gas Turbine Blades [PDF]
Volume 4: Heat Transfer; Electric Power; Industrial and Cogeneration, 1995 This paper presents a one-dimensional model to calculate the cooling flow of fully impingement cooled blades. The coolant is assumed to be ejected through a jet array running along the whole blade chord, with crossflow in the blade-to-blade plane from the leading edge toward the trailing edge.
