Abstract

The properties of cylindrical and spherical ion-acoustic shock waves are examined in multielectron temperature collisional plasma. Cylindrical and spherical Korteweg–de Vries–Burger (KdVB) equations for ion-acoustic shock waves are derived taking into account the ion viscosity and the ion heat conductivity and their numerical solutions are obtained. For weak dissipation and thermal conductivity an analytical expression for the cylindrical KdVB solution is obtained. Also the effects of ion viscosity and heat conductivity on the properties of shock wave are studied.
