The radial self-similar expansion of a dusty plasma is investigated in the cylindrical and spherical geometries. The electrons and ions are assumed to be in Boltzmann equilibria, while the dynamics of the dust particles are governed by the fluid equations. The effects of finite dust temperature and dust charge vari-ation on the self-similar expansion are examined. The variation of various plasma parameters, such as electron, ion and dust densities, dust flow velocity and dust charge, as a function of the self-similar variable are studied.
