 Abstract:
The modeling of plasma torch operation has advanced greatly in the last fifteen years due to a better understanding of the underlying physics, development of commercial, open-source computational fluid dynamics (CFD) software, and access to high performance and cloud computing. However, the operation mode of the electric arc in plasma torches is controlled by thermal, electromagnetic, acoustic and chemical phenomena that take place at different scales and whose interactions are not completely understood yet. Even through no single model of plasma torch operation fully addresses these phenomena, most of these models are useful tools for parametric studies, if their use is underpinned by knowledge of torch operation and the model predictions are validated against experimental data. To increase the level of predictability of the current models, several further steps need to be completed. This study will discuss the main issues that are still to be addressed in the modeling of plasma spray torch operation and the current critical aspects of these issues.
