【Abstract】 A mathematical model is presented to describe the fluid flow, the electromagnetic, heat flow phenomena. A computer program is developed to simulate the fluid properties of low power plasma torch. The purpose of this project is to provide a fundamental basis for predicting plasma behavior and particle velocity and heating properties in and out the torch.更多还原
