Turbulent collectivization processes of new ions at Venus and Mars and problems of numerical models of solar wind interaction with these planets

This paper deals with the mass-loading near Venus. It is shown that heavy ions produced from neutral atmosphere upstream the shockfront of Venus do not change essentially solar wind (SW) parameters (in particular, Mach number). In the Venusian magnetosheath the number of heavy ions undergoing the acceleration in the large-scale field which can be the source of the asymmetry and of the nonhydrodynamic properties of plasma is a few percents of the total ion flux from the dayside to the downstream mantle. The most intensive mass-loading of the SW flow is near the ionopause. The plasma with two ion species will have hydrodynamical features due to the turbulence resulting from instabilities
