| Abstract: | Additional sources method was adopted for the simulation on the outer blade wall heat transfer coefficient and the temperature distribution. The FORTRAN code has been used to research the internal heat transfer characteristics, the thickness of the blade wall and the thermal barrier coating（TBC） were also considered. The research of heat transfer characteristics and cooling performance of the gas turbine were valuable to understanding the advanced gas turbine cooling blade techniques. |
