Abstract

The article is devoted to mathematical modeling and numerical studies of accelerating flows of dense hot plasma in coaxial high-thrust plasma thruster channels, which can be used for the propulsion of large spacecrafts in outer space. Plasma is considered a continuous electrically conducting medium, whose behavior is described by magnetohydrodynamics (MHD) equations in disregard for dissipative effects. The paper employs a two-dimensional axisymmetric mathematical model based on non-stationary ‘‘ideal’’ single-fluid MHD equations. This model has been implemented numerically using a program code, with one of the major results being the application of parallel programming techniques to increase computational speed. This parallel code has been verified through a series of simulations investigating the influence of channel geometry on axisymmetric accelerator plasma flow parameters in coaxial channels.
