摘要
提出了变形流体网格两步法并对可压缩气体非稳态控制方程进行了数值求解，此方法可解决 跨音速、冲击波共存的情况．对ＳＦ_６断路器开断过程中灭弧室内粘性气体的流动特性进行了数值计 算，给出了在触头开断过程中气流特性的分布情况，解决了ＳＦ_６断路器灭弧室内具有大畸变的粘性 流体的数值计算．并对灭弧室开断小电容性电流后的介质恢复强度进行了计算．
A new method called two steps various shape FLIC method has been presented, which can be used to slove two dimensional axisymmetric Euler equations and applied to the coexistence of the transonic and shock wave. Gas flow has been calculated. The distribution of the flow characteristics with contact movement is given. The computational process of the complicated flow field with strongly irregular variations for the viscous flow in the interrupter of SF_6 circuit breaker is given. At the same time, the dielectric recovery characteristics of SF_6 are extinguished chamber after the interruptions of the small capacitive current is calculated.
