Abstract�� An integral analysis of momentum and thermal boundary-layers was used to determine the convective heat transfer coefficient on two-dimensional airfoils with thermal anti-ice system. The objective are to implement two different boundary-layer models: one assumed isothermal surface with prensence of a abrupt laminar-turbulent transition, while the other considered the boundary-layers over a non-isothermal surface with a smooth laminar-turbulent transition region. The onset and length of laminar-turbulent transition was estimated by classic empirical correlations. The surface equilibrium temperature distribution was predicted by an integrated airoil leading-edge interior-exterior thermodynamic analysis, compared to the literature and experimental data. The results indicate a validity of using boundary-layer anaylysis with smooth laminar-turbulent transition in predicting anti-icing convective heat transfer and surface temperature, but the simulation shows that surrounding static pressure has a large effect on the results accuracy.
