Shielding of a Moving Charged Dust Particle in the Nonequilibrium Plasma

Abstract

Study of shielding of a moving charged dust particle in the nonequilibrium plasma was performed. It is known that in the collisionless so‐called Vlasov plasma the electric field of a slowly moving charged particle at high distances corresponds to quadrupole [1, 2, 3]. It was found that in the collisional plasma the electric field of a moving dust particle had the dipole component and the long distance behavior of the electric fields was defined by this component. Therefore the interaction of dust particles in plasma flow became dependent on the relative orientation of the interpaticle radius‐vector and the flow velocity vector.
