Simulation Research on Characteristics of Paint Deposition on Spherical Surface

[摘要] In order to describe the gas-liquid two-phase coupling flow process of paint deposition on spherical surface, the Euler-Lagrangian method is adopted to establish the model of paint deposition on spherical surface, including continuous phase model, discrete phase model and impingement and sticking model. By comparing and analyzing the simulation results of flat and spherical surface in XZ-plane, the uniformity of the paint film on spherical surface is better than that on flat. As the spherical surface diameter increases, the distribution range of the paint film expands, the film thickness decreases, and the deposition rate improves. The characteristics of paint deposition on spherical surface are verified by experiments.
