Some features of dynamics of ensemble of the technogenic microparticles instantaneous injected in a near-earth space by the point source moving on the elongated elliptic orbit with a low perigee

Abstract

The computer program modeling the evolution of an ensemble of certain number of noninteracting spherical man-made microparticles is developed. In this case, we assumed that all particles have certain radius and are injected instantly by point source, which is moving on given trajectory in the NES. Particle initial velocities is defined by casual selection realized computer with correspond to given initial velocity distribution of injected particles. We suppose that injection is isotropic and injection velocities are uniformly distributed in given interval in the reference system of injector. The ensemble current state is determined by calculation of ensemble particles locations with the help of numerical solving of the single particle motion equations. These equations take into account that microparticle is influenced by the central gravitational field of the Earth and its perturbation caused by the polar compression of the Earth; force of the solar pressure; the upper atmosphere resistance force and electrodynamics forces.
