The thin runback water films driven by the gas flow, the pressure gradientand the gravity on the iced aircraft surface are investigated in this paper. Athree-dimensional film flow model based on Finite Volume Method (FVM) and thelubrication theory is proposed to describe the flow. The depth-averagedvelocity of the film is stored in Cartesian coordinates to avoid the appearanceof the metric tensors. The governing equations are discretized in the firstlayer structured grid cell which is selected as the grids for film flow. Inorder to verify this method, comparisons between numerical results andexperimental results of ice shapes on NACA 0012 airfoil and GLC-305 swept wingare presented, both showing a good agreement for rime and glaze ice condition.Overall, this model shows great potential to model ice accretion reasonablyunder different icing conditions. Besides, the present method doesn't requireanalytic metric terms, and can be easily coupled to existing finite volumesolvers for logically Cartesian meshes.
