Abstract: The paper presents the results of three-dimensional numerical simulations of high-velocity plasma jet outflows. The computational approach is based on a homogeneous finite-volume scheme implemented on unstructured tetrahedral mesh. For simulating rarefied flows with a Knudsen number of the order of unity, an efficient variant of a flux-correction method is proposed. The study investigates the symmetry of jet flows under injection at various angles. The potential application of the proposed methodology to the analysis of multiple plasma jet injection scenario is also discussed.

Keywords: plasma injection, flow symmetry, flux-correction technique, unstructured meshes, 3D modeling.
