| Abstract: | It is well known that a stable corona of ionized oxygen forms in the proximity of electrodes within powder coating pistols. What remains unclear though is the extention and shape of the ionized oxygen field, as well as its interaction with geometric boundary conditions. Therefore a Eulerian charge transport model was created within OpenFoam. It considers convective, diffusive and electro-static effects on charge distribution, as well as a dynamic coupling to the electric field. The latter is shown to be essential for obtaining a stationary solution, which amounts to a stable corona. Analysis of the result reveals unexpected yet plausible charge distribution effects within the application. The solution is validated by comparison to the point-wise measurement of potential field strength evolution on the outside of the pistol. Furthermore the new model is applied within a coupled powder coating solver which includes flow-, electric- and particle dynamic effects. This Multiphysics solver is then used to predict the corona-effect on particle charging-efficiency, as well as to compare pistol-design options and their respective impacts. |
