THERMAL CONDUCTIVITY DURING THE EXTERNAL COOLING OF GAS turbine rotor blades,
Abstract
An analysis of problems encountered in the development of internal cooling of rotor blades suggests that it may be possible to cool them by an external cooling method without changing the rotor design. To investigate the problem of external cooling, a study was made of the mean integral temperature of a plate in a quasi-steady-state to determine how much the temperature of a hot-plate will drop in a medium with periodic variations in the temperature and the heat transfer coefficient. It is concluded that due to the small fluctuation of the plate temperature, external cooling of turbine blades is practical. (Author)
