It was assumed that the temperatures of ions and electrons and the density of neutrals are constant. In this case, instead of finding the eigenfunctions and eigenvalues ​​of the problem mentioned, the Cauchy problem was solved for the initial values ​​given in the center of the plasma. The position of the wall was determined from the condition of equality of ion and electron fluxes. A method for solving the problem of singularity present in the system of equations of magnetic hydrodynamics is proposed. Estimates of the effect of ion viscosity in the equation of ion motion are estimated. Distributions of plasma parameters taking into account the viscosity of ions in the quasi-neutral approximation are obtained. Product Description popup.authors YELISEYEV Yuriy M.
