Modelling of Laminar Plasma Jet Impinging on a Flatplate with Approximate Box Relaxation Method

摘要

Approximate Box Relaxaiton method was used to simulate a plasma jet flow impinging on a flatplate at atmospheric pressure, to achieve a better understanding of the characteristics of plasma jet in materals surface treating. The flow fields under different conditions were simuilated and analyzed. The distributions of temeprautre, velocity and pressure were obtained by modelling. Computed resutls indicate that this numerical method is suitable for simulation of the flow characteristics of plasma jet, and is helpful for understanding of the mechanism of the plasma-material processing.
