Abstract

A numerical model for conjugate heat transfer (CHT) simulation is established for a turbine blade with air cooling, and 3D heat transfer simulation is accomplished.Effects of different amount of cooling air on the surface temperature distribution, work, efficiency of turbine blade is studied. The results show that the surface temperature drops quickly with the increase of cooling air at beginning and then become mild, the blade work goes up,the efficiency goes down.
