Zusammenfassung: This invited talk focuses on a finite-volume based Eulerian-LaGrangian model created within OpenFoam®. Its purpose is to predict the behavior of particle clouds as well as particle deposition thicknesses on substrates under the influence of electro-static effects. The model resolves close-to-electrode effects as well as phenomena within the entire coating chamber. It considers fluid dynamic effects, particle inertia, gravity, electric- as well as mechanic particle-particle interaction, corona formation-, dynamic-particle-charging mechanisms and a coupling of particle motion to RANS based flow simulations. Resulting coating pattern predictions were experimentally validated. Qualitative and quantitative correspondence to measured coating -thicknesses and -patterns under the variation of i) applied voltage, ii) airflow rate, pistol-substrate iii) -distance and iv) –angle, can be demonstrated. Furthermore the software has been prepared such that it works on the cloud computing software KaleidoSim®, which enables the simultaneous browser-based running of hundreds of cases for large parameter studies.
