Calculating Temperature of Turbine Blades with Effusion Cooling,

Abstract

Calculations show that when the parameters of the working fluid are sufficiently high, internal convective cooling of turbine blades is ineffective. The temperature of the outer surface of the blade remains inadmissibly high and the temperature gradient in the sleeve is too great. It is for this reason that the effusion method of cooling the flow part has been the subject of ever increasing attention. The outer wall of the turbine blade (sleeve) is made in this case of a permeable sheet material, permitting a constant flow over the blade.
