“…The anomalous dissipation leads to preferential importance of shock waves in dusty plasmas, which have specific features that distinguish them from ordinary collisional and collisionless shock waves. That dust ion acoustic shock waves associated with anomalous dissipation can actually exist was proved analytically by Popel et al (1996Popel et al ( , 2001Popel et al ( , 2005 and experimentally by Nakamura et al (1999) and Luo et al (1999).…”

Abstract.The results on shock phenomena in dusty plasmas of the Solar System are reviewed. The problems of dust ion acoustic bow shock in interaction of the solar wind with dusty cometary coma and formation of transient atmospheres of atmosphereless cosmic bodies such as Moon, Mercury, asteroids and comets are considered. The latter assumes the evolution of meteoroid impact plumes and production of charged dust grains due to the condensation of both the plume substance and the vapor thrown from the crater and the surrounding regolith layer. Physical phenomena occurring during large meteoroid impacts can be modeled with the aid of active rocket experiments, which involve the release of some gaseous substance in near-Earth space. New vistas in investigation of shock processes in natural dusty plasmas are determined.

“…Usually, it is negatively charged. 12,13 Many interesting phenomena have been found in dusty plasma. For example, the dust acoustic wave was reported first by Rao et al 14 Later, Shukla and Silin showed the existence of the dust ionacoustic wave in higher frequency in unmagnetized dusty plasma.…”

The effect of the dust size distribution on the damping rate of the solitary wave in a dusty plasma is investigated in the present paper. It is found that the damping rate increases as either the mean radius of dust grains increases or as the total number density of the dust grains increases. The damping rate is less for usual dusty plasma (about which the number density of the smaller dust grains is larger than that of the larger dust grains) than that of the unusual dusty plasma (about which the number density of the larger dust grains is larger than that of the smaller dust grains).

“…The dissipation in dusty plasma, which originates from the dust particle charging process, makes existence of a new kind of shocks related to this dissipation possible. 37,38 By considering the dissipation among the plasma constituents, one can derive Korteweg-de Vries-Burgers (KdVB) equation which has shock solution. The effects of electron circulation in the shock front were discussed in Refs.…”

Nonlinear features of ion acoustic shock waves in dissipative magnetized dusty plasma

The nonlinear propagation of small as well as arbitrary amplitude shocks is investigated in a magnetized dusty plasma consisting of inertia-less Boltzmann distributed electrons, inertial viscous cold ions, and stationary dust grains without dust-charge fluctuations. The effects of dissipation due to viscosity of ions and external magnetic field, on the properties of ion acoustic shock structure, are investigated. It is found that for small amplitude waves, the Korteweg-de Vries-Burgers (KdVB) equation, derived using Reductive Perturbation Method, gives a qualitative behaviour of the transition from oscillatory wave to shock structure. The exact numerical solution for arbitrary amplitude wave differs somehow in the details from the results obtained from KdVB equation. However, the qualitative nature of the two solutions is similar in the sense that a gradual transition from KdV oscillation to shock structure is observed with the increase of the dissipative parameter.
