dc.description.abstractA computational fluid dynamic model of the powder coating process has been developed using OpenFoamĀ®. It considers particle-dynamic-, aerodynamic-, electro-static- and gravitational effects. While being fully functional, the Eulerian-LaGrangian model has in some cases shown anomalies, yielding coating predictions, which were not observed in comparable experiments. In order to analyse and amend the problem, the underlying Reynolds Average Stress (RAS) turbulence modelling approach was (i) re-evaluated, compared to (ii) Direct Numerical Simulation (DNS) and (iii) Large Eddie Simulation (LES) flow modelling methods, (iv) improved to account for turbulence impact on flow-particle interaction and (v) extended by a dynamic particle charging algorithm. The effects of the said model improvements were investigated and model-results were compared to measurements of experimentally obtained coating thickness values. It can be shown that the modified simulation model yields a much higher level of correspondence to experiments than previous versions.de_CH
