Jets acceleration in a variety of matter source modelling ways

MHD-model of astrophysical jet outflow from the vicinity of compect object surrounded by thin accretion disk and encloused into the galactic plasma cloud is considered. Numerical algorythm based on the division by physical processes and including finite difference scheme for MHD system of equations in axissymmetric two-dimensional case is constructed. Triangular unstructured staggered grid is used. Results of modelling show the formation of accelerating channel in the shape of Laval nozzle. Results are in agreement with observational data. Calculations are made on KIAM K-100 cluster.
