In this paper, the heat transfer to the annular cavity of the engine casing is researched through three-dimensional numerical hydrodynamics method and one dimensional heat transfer calculation method. The flow characters and flow distribution of annular cavity, radiation calculation model and convection heat transfer law are studied as well. And the method to the research was verified through eat transfer test data of engine test run. Finite element numerical simulation and sector model can be used in this research and accurate flow heat transfer law can be obtained.
