Abstract
The development of a general method for calculating unsteady heat transfer on turbine blades is described. It is based on the numerical solution of the boundary-layer equations for laminar, transitional, and turbulent flows. A novel procedure has been developed to account for the movement of the stagnation point caused by blade-passing wakes and has been applied to the stagnation region of three model flows with results which confirm its validity for laminar flows. It has also been applied to an experimental arrangement in which the average Nusselt number has been reported for turbulent flows and the results show considerable promise.
