Research on spraying models of special profiles has a great significance on optimizing spraying quality, saving paint and protecting environment and health of workers. This article establishes a paint deposition model including the spray flow field model and impact adhesion model based on the Euler-Euler method. The model is solved by using polyhedral mesh to divide the fluid calculation domain and the coupled SIMPLE algorithm to compute the governing equations. The methods of spraying along the bus bar and circumferential spraying are applied to simulate and test the conical surface and the arc surface successively. Results of the experiments demonstrate the errors of the four cases are all less and confirm that the established paint deposition model is suitable for spraying research on conical outer surface.
