2D modeling of ion shadow behind a charged satellite by the method of molecular dynamics



It was considered a two-dimensional model of the interaction of a charged micro satellite and thermal plasma. The method of molecular dynamics used as a modeling method. Ion concentration distributions near SC were calculated for 10 and 102 protons in cm2 and the two values of relative satellite velocity and plasma were considered — 8 and 20 km s-1, respectively. It is shown that an increase in velocity and concentration of particles of ion shadow behind the satellite becomes more expressed.
