In this paper a numerical simulation of electrostatic spray-painting with movement of the atomizer has been performed using dynamic mesh models. As atomizer the high-speed rotary bell with external charge was used. Simple movement of the atomizer and simple geometry of the substrate were considered. Numerical results with two different dynamic mesh models, i.e., dynamic layering and local remeshing are discussed. The simulated film thickness distribution was compared with the experimental result.
