摘　　要：应用Ｔａｙｌｏｒ－Ｇａｌｅｒｋｉｎ法对可压缩气体非稳态控制方程组进行了数值求解，计算了ＳＦ６压气式断路器灭弧室在不同压比、不同喷口形状下的流场分布．通过对计算结果的分析。The Taylor Galerkin finite element method was used to solve unsteady two dimensional axisymmetric Euler equations. SF 6 gas flow fields in the arc chamber with different nozzle shapes and different ratios of reservoir pressure to exit pressure were given. The dielectric recovery characteristics of SF 6 arc chamber in these conditions after the interruption of a small capacitive current were investigated.
