Properties of compressible flows in the quasi‐stationary plasma accelerator have been studied in the presence of an additional longitudinal magnetic field and the arising rotation of plasma flow. Numerical study was carried out within the framework of two‐dimensional magnetic hydrodynamics (MHD) model of the axisymmetric plasma flows taking into account the finite conductivity of medium and radiation transport. Dynamics of compressible plasma flows is accompanied by the MHD dynamo effect or generation of magnetic field on a conical shock wave forming at the outlet from the accelerator.

纵向磁场存在下等离子加速器出口处的MHD发电机效应研究

研究了准静态等离子体加速器中可压缩流动的性质，该流动存在附加的纵向磁场和产生的等离子体流动旋转的情况。考虑到有限的电导率和辐射传输，在轴对称等离子体流的二维磁流体动力学（MHD）模型的框架内进行了数值研究。可压缩等离子体流的动力学伴随着MHD发电机效应或在加速器出口处形成的圆锥形冲击波上产生磁场。
