| Abstract: | After having developed and validated a Eulerian-Lagrangian simulation model for powder coating applications, the novel OpenFoam® based tool has been steadily enhanced, adapted and improved. In accordance with statistically valid observations from extensive experimental series, various sub-models have been devised in order to further increase the predictive quality of the software. In the course of this improvement- and adaption process i) an efficient scheme to achieve accurate fluid-particle coupling has been introduced, eliminating experimentally non-observable coating imprints on the substrate, ii) a method to realistically predict particle motion close to substrate surfaces as well as particle-surface sticking behaviour has been devised and finally iii) a semi-implicit dynamic particle-charging algorithm has been developed to account for corona-particle charging effects. On the basis of these improvements, solver predictions have become accurate enough to now provide never-before achieved insight into phenomena and parameter dependencies of the powder coating process. In particular the model has greatly helped to better understand connections between coating efficiency as well as coating quality and parameters like applied voltage, volumetric air-flow rate, substrate-pistol distance and substrate-pistol angle. These results constitute the basis of a variety of possible powder coating process improvements in the near future. |
