Abstract:
Numerical study of the ionization process and radiation transport in a flow of ionizing helium in the channel of the quasi-stationary plasma accelerator is presented. The model of two-dimensional axisymmetric flows is based on the modified MHD equations for the multicomponent medium consisting of atoms, electrons, and multiply charged ions with different ionization multiplicity. The numerical model takes into account the electrical conductivity and thermal conductivity, and the 3D model of radiation transport includes the main mechanisms of radiation and absorption for different parts of the spectrum. The spectral field of radiation and its integral characteristics in the forming transonic stream of helium plasma are determined.
Keywords:
equations of magnetogasdynamics, radiation transport, flows of
ionizing helium, plasma accelerator.
