Abstract: Up until today the development of many powder coating applications rather relies on trial and error methods than on knowledge-based optimization. In order to create the foundation for introducing model-based engineering methodology within the field, a detailed, validated model of the powder coating process has been created. It features a coupled solution of electro- static, fluid- and particle-dynamic effects that govern particle motion and deposition phenomena. In contrast to previously published standards, this recently completed software is capable of considering electro-static particle interactions and transient particle loading effects close to the electrode. Thus the simulator is specifically suited to optimize not only particle deposition efficiency at the substrate, but also to work out and compare pistol design options in terms of maximized particle surface charge density. Since the development effort has been closely accompanied by the conduction of coating experiments in a small coating chamber, a relatively wide range of validating data can be presented alongside the model. Simulations can now be used to develop coating equipment, which will accomplish better coating quality as well as higher coating efficiency.
