In this paper we analyze the model that describes the evaporation process of multi-size\n(polydisperse) of fuel droplets in a laminar boundary layer flow. The spray is described\nusing a probability density function and is based on the well-known sectional\napproach. The spray is described in two dimensional boundary layer directions that\nconsists of five equations: the continuity equation, the momentum equation, the\nenergy equation, the equation of state and the spray equation. The governing equations\nare a system of nonlinear partial differential equations (PDE). In order to convert\nthe PDE to ordinary differential equations, we applied the Lees-Dorodnitsyn similarity\ntransformation and the corresponding similar solution based on the compressible\nstream function. We then solve the model numerically and compare our results to the\nsectional approach with an experimental data.
