等离子体喷射轴心铝丝的磁流体动力学模拟

 采用一维拉格朗日磁流体力学（MHD）程序研究了等离子体喷射轴心单丝的物理现象，给出了碰撞后铝丝受热膨胀和最后箍缩到轴心的整个过程图像，指出这一设计方法能在轴心丝上获得较高的电流上升率和较高的轴心压缩密度，并还给出了箍缩所得的功率和能量曲线。

Simulation of magnetohydrodynamics for plasma jetting on wire pinch

For a deeper understanding of the physical process of plasma jetting on wire an one dimension magnetohydrodynamics simulation code under Lagrangian coordinates was used. It is detailed that the axial Al wire heated by shock wave expends after collision and finally pinches on the axis. A large value of current raise rate is got on the axial wire according to the calculations. The resultant pinch outputs more X-ray energy and higher power.
