Self-consistent expansion of a multicomponent plasma in vacuum

The problem on the one-dimensional noncollisional expansion of the multicomponent plasma into vacuum is considered. The approximate analytical solution for the arbitrary set of ions with the masses M1,...,Mn and charges Z1e, Z2e,...,Zne is found in the hydrodynamic approximation. The solution is based on the method of the self-modeling variables previously used for the case of the single-type ions. The numerical iterative algorithm applying the analytical solution as the first approximation is plotted
