| Abstract: | 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 gas 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 SF6 ciriuit breaker is given. At the same time, the dielectric recovery characteristics of SF6 arc extingusihed chamber after the interruption of the small capacitive cunent is calculated. |
