Stationary velocity and charge distributions of grains in dusty plasmas
Within the kinetic approach the velocity and the charge distributions of grains in stationary dusty plasmas are calculated and the relations between the effective temperatures of such distributions and plasma parameters are established. It is found that the effective temperature which determines the velocity grain distribution could be anomalously large due to the action of accelerating ionic b...
متن کاملVelocity-Dependent Friction and Diffusion for Grains in Neutral Gases, Dusty Plasmas and Active Systems
A self-consistent and universal description of friction and diffusion for Brownian particles (grains) in different systems, as a gas with Boltzmann collisions, dusty plasma with ion absorption by grains, and for active particles (e.g., cells in biological systems) is suggested on the basis of the appropriate Fokker-Planck equation. Restrictions for application of the Fokker-Planck equation to t...
متن کاملSectional modeling of nanoparticle size and charge distributions in dusty plasmas
Sectional models of the dynamics of aerosol populations are well established in the aerosol literature but have received relatively less attention in numerical models of dusty plasmas, where most modeling studies have assumed the existence of monodisperse dust particles. In the case of plasmas in which nanoparticles nucleate and grow, significant polydispersity can exist in particle size distri...
متن کاملDusty Plasmas' The Effect of Closely Packed Grains
A dusty plasma device recently described in the literature has been utilized to study experimentally the charging of dust grains by the surrounding plasma. By varying the ratio d/A D between the intergrain distance and the plasma Debye length, the effects predicted by Goertz and Ip (1984), and subsequently reanalyzed in a more general fashion by Whipple et al. (1985), when "isolated" dust grain...
متن کاملEffect of charge reduction on shielding in dusty plasmas
The shielding of dust particles by each other in a dusty plasma is studied taking into account the effects of dust charging. It is shown that the assumption of a Boltzmann response for dust species is not appropriate under these circumstances. Further, it is shown that in the close-packing limit, dust grains screen each other by charge reduction, and an expression is obtained for this shielding...
