In the modelling of non-transferred plasma torches, the electrical potential is normally used in the same way as in the simulation of transferred plasma torches. This approach results in physically questionable current density profiles. A modification is proposed in the manner that the electrical potential is used in the simulation of non-transferred plasma torches. The new model provides in physically acceptable results. A comparison of the results obtained from the two models (the previously used and the presently proposed), shows differences of up to 50% in the velocity and 20% in the temperature were found. Tests were performed with the new model showing the possibility of using it for a broad range of parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
