【Abstract】 Ablation capillaries plasma generator is a basic composition element in an electrothermal launching system. For a standard ablated material—polyethylene, one dimentional governing equations for the plasma generator were established and solved with the MacCormack explicit implicit method. Characteristic parameters of discharge and the process of one dimensional flow in the plasma generator were calculated. Through experiments the hypothesis and model were confirmed. This model can be used for forecasting the performance of the plasma generator.更多还原
