Abstract linear and nonlinear dust acoustic da waves are studied in a collisionless unmagnetized and dissipative dusty plasma consisting of negatively charged dust grains boltzmann distributed electrons and nonthermal ions. Download citation on researchgate nonlinear acoustic waves in nonthermal dusty or pair plasmas using a sagdeev pseudopotential formalism where nonlinear structures are stationary in a comoving . The linear and nonlinear properties of low frequency motion in inhomogeneous magnetized dusty plasmas are investigated the dynamics of the dust grains are taken into account by means of a fluid model a new type of low frequency waves the dust drift waves is shown to exist. In recent years the study of nonlinear waves in plasmas has become one of the most important topic in plasma physics 12 also a number of authors have in vestigated properties of one dimensional linear and nonlinear dust acoustic waves daw in coupled unmagnetized dusty plasmas rao et al theoretically predicted. Therefore it is paramount to study linear and nonlinear waves in various configurations of laboratory and space plasma 4 14 19 46 nonlinear dust acoustic solitary and shock waves in plasmas have a considerable attention to study the propagation behaviour of the nonlinear waves
