Heat transfer and cooling technology play an important role in gas turbine as well as other hot part of modern thermo power plants. Implement film cooling to protect the surface of a blade, the air flow in the internal of the blade to take away the heat conducted in. all the technology should be harmonize to minimize the difference of temperature for lower thermo stress while achieve best cooling effect with cooling air as less as we can. The air system performance, such as seal, shaft force and system analyze, are also the area which focus on.
