Abstract�� It is the premise and basis of thermal structure analysis to determine the temperature distribution of combustor liner. The three dimensional temperature distribution of a combustor liner was captured by the numerical simulation of an annular return-flow combustion chamber with ANSYS/CFX based on the thermal-fluid-solid coupling finite element method (FEM). The calculation analyzes the effect of heat source and heat radiation, the influence of variable flow field on heat exchange parameter, and the change of the parameters of gas, kerosene, solid with temperature were taken into account. The numerical simulation results demonstrate that the interaction between the flow field and solid wall is more sufficient comparing with traditional methods. The complete feature of flow field and temperature field could be reflected, and the distribution of flow field and temperature field and corresponding flow and heat transfer characteristics could be simulated reasonably. The work is significant on the application of structure design of combustor liner.
