Effects of damping solitary wave in a viscosity bounded plasma

In this paper, the propagation of solitary waves in a bounded plasma is theoretically investigated in terms of finite geometry. We employ the reductive perturbation theory to derive a quasi KdV equation, which characterizes the damping solitary wave in terms of kinematic viscosity coefficient v' and radius R. It is noted that the damping rate increases as v' increases or R decreases. We also observe the existence of damping solitary wave from the fact that its amplitude disappears rapidly for R -> 0 or v' -> +infinity. (C) 2014 Author(s).
