| 摘 要： | 结合火箭模型和雪耙模型，建立了完整自洽的丝阵Z箍缩消融-内爆模型，分析了消融等离子体对丝阵Z箍缩内爆动力学的影响，得到了比零维薄壳模型合理的内爆轨迹。在考虑消融等离子体向轴运动的情况下，计算了丝阵Z箍缩的内爆时间、内爆速度和动能，并且与零维薄壳模型进行了对比。结果表明，考虑消融等离子体运动得到的内爆动能低于零维薄壳模型计算结果，其内爆动能最大值所对应的负载线质量也低于薄壳模型。

| Abstract: | A self-consistent ablation-implosion model was established in which Rocket model and snowplow model were well combined.The effects of ablated plasma on the implosion dynamics of wire array Z pinches were studied and a rational implosion trajectory was obtained.The implosion time,velocity and kinetic energy were calculated and the results were compared with that of the zero-dimension thin shell model.It was found that the implosion kinetic energy and the mass of wire array(per unit length) for the maximal ki... |
