A numerical and analytic study of film formation and evolution during spray impingement is presented. For the part of the film which excludes drop impact locations, the governing equations reduce to a convenient form that can be exploited using a Lagrangian particle method. At impingement points the source terms for mass and energy are calculated based on conservation principles and phenomenological results. It is shown that during the period where most of the film evolution takes place, the effect of gas shear and surface tension are negligible. Numerical testing is performed to ensure convergence. Comparisons to spray impingement experiments consisting of film extension and thickness measurements yield reasonable agreement with the exception of the shallow angle impingement case where it is suspected that the total mass deposited is overpredicted.
