The effect of mass forces on heat transfer in turbine rotor blades and on hydraulic resistance in cooling channels
Abstract
The results of an investigation of local heat transfer between gas and turbine blades are given in the paper. The method of unsteady heat regime of thin wall is used to determine local heat flows. The heat transfer coefficients obtained both for rotating and fixed blades are compared. The effect of non-isothermal flow in rotating rotor systems on heat transfer and hydraulic resistance is analyzed. The qualitative coincidence of heat transfer coefficients and hydraulic resistance in rotating radial and fixed vertical ducts is acknowledged.
