| Abstract: | An MHD model of the formation of astrophysical jet outflow from the vicinity of a compact object surrounded by a thin accretion disk and immersed into the nebula of a galactic plasma is considered. The numerical algorithm is based on division by physical processes and includes a difference scheme for the MHD system of equations in the two-dimensional (2D) axisymmetrical case. Triangular unstructured staggered grids are used. The modeling results show the formation of the accelerating channel in the shape of a Laval nozzle and comply with the available observation data. Computations are performed on a KIAM K-100 cluster. |
