摘要
采用一维单流体双温度辐射流体动力学模型.通过数值模拟方法.研究了XeCl准分子激光辐照金属Al靶时.气化等离子体的形成和演化过程.
Based on a one-fluid, two-temperature radiation hydrokinetics model, we study the interaction processes of XeCl laser radiation with a one-dimensional aluminium target. The heating processes of the target are described by nonlinear thermal conductive equations. The forming and evolution processes about the densities and the temperatures of laser-generated plasma are govened by the rate equations. According to this model, we give out the numerical code. Our results present the physical pictures of different stages about the plasma evolution. The impulse coupling coefficient agrees fairly well with the experimental results in literature.
