|Abstract:||In industrial applications involving particle-laden flows such as powder coating, often ad-hoc heuristic methods are employed to design or adjust processes in light of varying process-parameter settings. This labor-intensive approach often leads to inefficiencies and sub-optimal outcomes, as the entirety of the design space is not taken into consideration. The alternative, much more efficient approach entails knowledge-based process adjustments. However, the latter is often beyond the capabilities of industrial appliers, since it requires an extensive expertise and highly skilled labor force. The numerical Multiphysics-simulation software coatSim has been designed in order to bridge the gap between the required expertise and the need for a predictive tool for industrial knowledge-based process design. coatSim is a user friendly, cloud-based simulation software that can be customized for any industrial application involving flows laden with solid or liquid particles or indeed ionic transport mechanisms. Its core technology relies on an OpenFOAM based, Eulerian-Lagrangian solver, where particle flow-paths, particle-particle and particle-substrate interaction effects can be modeled in light of acting fluid dynamic-, and body forces as well as particle dynamic effects. In the case of powder coating applications, the body forces are the electrostatic forces generated by the coating pistol and gravity. The solver has been validated on the basis of an experimental campaign, where substrate plates were coated in 72 configurations. Thereby measured relative coated volume could be predicted up to a variation of 5%. The underlying solver can handle domains comprised of several independent mobile regions, on each of which a periodic motion in terms of any arbitrary Fourier series can be imposed. This enables realistic duplication of industrial applications, as motion is an intrinsic part of most of them. The core solver technology has been bundled with an intuitive user interface containing application specific databases, geometry manipulation tools and automatic mesh generation capabilities. Hence the user can generate a simulation case with minimal effort and as a next step expand it into a parameter study by prescribing the values of relevant parameters to vary. The software is directly coupled to cloud computing facilities to harness massive simultaneous cloud computing functionality.|
