| Zusammenfassung: | The abilities of Kaleidosim, a Massive Simultaneous Cloud Computing (MSCC) platform and of a Eulerian-Lagrangian finite-volume OpenFOAM-based solver were combined within the powder coating simulation software CoatSim. While the OpenFOAM solver can model Multiphysics corona-formation effects as well as Lagrangian particle-based spray-cloud evolution between coating pistols and electrically grounded metallic substrates, the MSCC capability allows for the simultaneous cloud-based computation of hundreds of process-parameter-scenarios. CoatSim simulates the fluid dynamics of process airflow, coating-particle-dynamics, fluid-particle, particle-particle and highly detailed particle-substrate interaction including blow-off effects, corona formation around the high voltage electrode as well as particle charging mechanisms within the corona. Previous works have demonstrated the practical relevance of the software in terms of qualitative and quantitative validation against hundreds of coating experiments. In addition a comprehensive graphical user-interface was recently added, further increasing its practical applicability. In the current study, CoatSim is applied to compare actually thousands of process-parameter scenarios for the powder coating of U-profiles, which, due to Faraday-cage effects, have always posed a certain challenge for powder coating. More specifically the focus of this study lies on investigating the impact of varying process parameters on key-performance-attributes of the process. The process parameters to-be-varied are: i) applied voltage, ii) primary- and secondary- process airflow rate and iii) particle-charging-function-factors. The key-performance-attributes to be evaluated are: i) visualised coating-patterns, ii) coating-efficiencies, and iii) the relative standard batch-based coating deviation. Limiting investigations to static setups (= pistol not moving), single-pistol-, single-burst- scenarios and simplifying certain parameter-cross-dependencies, optimal U-profile coating-process-settings can be proposed. |
