By using the interface program, the calculation program of flow and heat transfer of air system developed by Northwestern Polytechnical University, the calculation program of heat exchange between turbine blades and the thermal calculation module of commercial software Ansys12.0 are organically integrated to realize the convective heat transfer between inner and outer surfaces of the turbine blades and Solid thermal coupling calculation to quickly obtain the three-dimensional temperature field distribution of turbine blades. By comparing the calculated results with the experimental data, the accuracy of the calculation method used is verified. The proposed calculation method can obtain 3D temperature field of turbine blade quickly and accurately and has important engineering application value for the design and optimization of turbine blade cooling structure.
