Dust acoustic shocks in viscous dusty plasma with polarization force

In present paper, the propagation of dust acoustic shocks are investigated in viscous dusty plasma including the effect of polarization force. The considered three fluid model is dealing with electrons, ions and negatively charged dust grains. In the governing model equations, the non-thermal ions distribution, Maxwell Boltzmann electrons and dust polarization force modified by the presence of nonthermal ion population are considered. Using the reductive perturbation method, Burger equation is obtained to study the characteristics of modified dust acoustic shocks analytically and graphically. The viscous and nonthermal polarization force significantly affects the propagation of dust acoustic shocks.
