Description
Summary:Wave properties of damped solitons in a collisional unmagnetized four-component dusty fluid plasma system containing nonthermal distributed electrons, mobile ions and negative-positive dusty grains have been examined. To study dissipative DIA mode properties, a reductive perturbation analysis is used under convenient geometrical coordinate transformation, a three dimensionally damped Kadomtsev-Petviashvili equation 3D-CDKP in cylindrical coordinates is obtained. The effects of electron nonthermality and collisional parameters on damped soliton pulse structures are studied. More specifically, the coordinate impact of axial, radial and polar with the time on solitary propagation are examined. This investigation may be viable in plasmas of the Earth's mesosphere.
