本文叙述了TIG电弧的一个较好的数学模型化研究方法。采用数值解的方法着重计算了各种条件对电弧中等离子流的影响。通过数值计算对等离子流速度分布、罗伦兹力的分布和电弧温度分布等都做了定量的描述。可使人们对TIG电弧中的各种变化有一个更清楚和更明确的概念。
This article describes a good mathematic modeling approach to TIG arcs. The influence of various conditions on the plasma flow in arc is emphatically calculated by the method of numerical solution. The distribution of plasma velocity, the distribution of the Lorentz force and the distribution of the arc temperature are quantitatively described by numerical calculation. There is a clearer and clearer concept of the variety of changes in a TIG arc.
