摘要

研究了细金属丝在水中爆炸的数值模拟问题。对于圆柱几何,采用状态方程和电导率的实表达式对流体动力方程组进行了数值求解。在数值计算的基础上,对计算结果与实验数据进行了比较。在相图上研究了水下脉冲放电过程中放电通道不同部位的状态变化。最后,对一些使用UPD能源的工艺装置进行了研究。

Underwater pulse discharge (UPD) and its technological applications
The numerical modeling of the explosion of thin metallic wires in water is considered. For cylindrical geometry the set of hydrodynamical equations was solved numerically using a real expression for the equation of state, and electrical conductivity. A comparison between calculation and experimental data was made based on the numerical results. changes of state for different parts of the discharge channel during UPD (underwater pulse discharge) on the phase diagram were examined. Finally, some technological units that use UPD energy are examined.<>
