The heat and mass transfer phenomena on the anti-icing surface of the wing are analyzed, and the heat and mass transfer coupling inside and outside the anti-icing surface is studied.The heat transfer coefficient of the wing surface is calculated by the method of surface layer integration.According to heat and mass transfer The surface evaporation of the anti-icing surface is obtained by comparison.The surface differential equations of energy and mass of the surface micro-element are established and solved by the Gauss-Seidel iteration method, the external ice-proof load, the chordal conduction of the skin and the internal heating heat flow are coupled, The sub-relaxation coefficient is used to stabilize the iterative process, and the range of equilibrium surface temperature, overflow water and overflow icing is finally obtained.The calculated results are in good agreement with those in the literature and other numerical simulations, which shows the correctness of the model and calculation method .
