Abstract
The nonlinear characteristics of shock structures have been investigated in dusty plasma consisting of inertialess Boltzmann distributed electrons, nonthermally distributed ions, and stationary dust grains with nonadiabatic charge fluctuation and arbitrary dust size distribution in present work. A Korteweg–de Vries (KdV) Burgers equation governing the dust acoustic shock structures is obtained by Reductive Perturbation Method. The relevance of shock waves’ evolution to the dust size distribution and nonadiabatic charge fluctuation is illustrated both analytically and numerically. The numerical results show that dust size distribution, and nonadiabatic charge fluctuation have strong common influence on the propagation of shock structures.
