| Abstract: | The coupled calculation model of flow field and temperature field was established on the base of analyzing the configuration of a turbofan engine cooling turbine blade. The simulation with coupling three-dimension fluid dynamics and a conduction heat transfer was conducted, the computation results of flow field and temperature field were gained and the cooling effect was analyzed. The application of coupled calculation in the design of cooling turbine blade was analyzed and discussed. |
