| Abstract: | Considering the interaction between water film flow and heat transfer on an anti-icing surface,a method to calculate the temperature of anti-icing surface was brought forward based on wet surface heat transfer and flow coupling.The surface temperature of a fully evaporated anti-icing airfoil was calculated with this method and the effect of each kind of heat flux on the wet surface was also analyzed.The results showed that surface temperature was very sensitive to heat transfer coefficient and highly influe... |
