论文摘要
粘稠的尘土高血浆中含有kappa分布的电子，阳性温暖的粘性离子和带粘度的恒定带负电荷的灰尘晶粒，用于研究理论和数值上尘埃离子声波（DIAWS）的模式。具有不同等离子体参数的冲击和孤立波的派生和基本特征，例如马赫数，有限温度系数，不受干扰的灰尘流速度，灰尘的运动粘度等。考虑到Korteweg de Vries（KDV）方程的动力学方程，已经绘制了相肖像以及鞍点或COL的位置。和中心也已被讨论。这种类型的灰尘等离子体可以在天体中找到。这项研究工作的结果可以应用于在存在Kappa分布电子的各种天体物理情况下DIAW的性质，并且对同一模型的仔细修改也可以帮助我们了解实验室血浆DIAW的性质。
A viscous dusty plasma containing Kappa distributed electrons, positive warm viscous ions and constant negatively charged dust grains with viscosity have been considered to study the modes of dust ion acoustic waves (DIAWs) theoretically and numerically. The derivations and basic features of shock and solitary waves with different plasma parameters like Mach number, finite temperature coefficient, unperturbed dust streaming velocity, kinematic viscosity of dust etc. of this DIAWs mode have been performed. Considering the dynamical equation from Korteweg de Vries(KdV) equation, a phase portrait has been drawn and the position of saddle point or col. and center have also been discussed. This type of dusty plasma can be found in celestial bodies. The results of this research work can be applied to study the properties of DIAWs in various astrophysical situations where Kappa distributive electrons are present and careful modification of the same model can help us to understand the nature of the DIAWs of laboratory plasma as well.
