A model of the polarization dust particles with trapped ions in an external electric field is presented. It based on self-consistent solution integral balance equation for ion density and Poisson potential. shown that, a low collisional regime, form spread shell maximum located at some distance from thecharged particle proportional to Debye length. The estimated polarizability dusty "quasiatoms...

This doctoral thesis reports analytical and numerical results for the electrostatic response of a dusty plasma to a moving test charge. Two important physical aspects of dusty plasmas, namely grain size distribution and grain charging dynamics were taken into account. In the first case, a dusty plasma in thermal equilibrium and with a distribution of grain sizes is considered. A size distributi...

Pinned solitons are a special class of nonlinear solutions created by supersonically moving object in fluid. They move with the same velocity as and thereby remain pinned to object. A well known hydrodynamical phenomenon, they have been shown exist numerical simulation studies but date not observed experimentally plasma. In this paper we report first experimental excitation dusty (complex) plas...

Strongly-coupled dusty plasmas often exhibit liquid behavior. Liquids behave as a viscous continuum in the hydrodynamic regime. However, in the kinetic regime of a liquid, viscous and elastic effects occur at the same time [1], i.e., the liquid is said to be viscoelastic. To characterize the viscoelasticity of a liquid, the complex viscosity, () = () i(), is often used, where the real a...

The relaxed state of a magnetized four-component partially ionized dusty (PID) plasma is explored. PID composed inertial electrons, positive ions, neutrals, and static negatively charged dust particles. When the neutrals are dragged along with steady-state solution vortex dynamic equations for electron ion species yields triple Beltrami state, which linear combination three single force-free fi...

The interest in complex plasmas is increasing due to the multiple applications they target (astrophysics, plasma fusion, industry, etc.). A crystal with two vortexes made of spherical microparticles that levitates an rf interacts a gas jet. displaced jet propagation direction neutral pushing force, maintaining its vortex structure. shift also involves change shape, especially at level vortexes....

The Liouville equation is considered for relaxing dusty plasmas consisting initially of equilibrium electrons and ions as well as neutral dust particles. The plasmas relax then due to a collection ofelectrons and ions by dust particles. The free and collected electrons and ions are considered as a common subsystem described by the common whole distribution function. It is shown that this sub-sy...
