Non-Linear Phenomena in Dusty Plasmas

A. J. Turski, B. Atamaniuk, E. Turska

摘要:

本文的主要目的是确定Vlasov-Ampere/Gauss方程组初值条件的渐近解,即寻找“远场”解。其次,我们确定色散关系的纵波(纵波和DIAW)通过使用线性化的弗拉索夫方程。在简化的平衡速度分布的情况下,但对于完全非线性等离子体,我们确定的速度分布,并通过使用Sagdeev势方程,我们计算的孤立和双层结构的尘埃等离子体参数。利用Sagdeev势,我们确定了等离子体双电层的电容。

英文摘要:

The main objective of the paper is to determine asymptotic solutions to the initial-value conditions for Vlasov-Ampere/Gauss system of equations that is to find the "far field" solutions. Next, we determine dispersion relations for longitudinal waves (DAW and DIAW) by use of the linearized Vlasov equations. In case of simplified equilibrium velocity distributions but for fully nonlinear plasmas, we determine velocity distributions and by use of Sagdeev potential equations, we compute the solitary and double layer structures for a set of dusty plasma parameters. By use of Sagdeev potential, we determine the electrical capacity of plasma double layers.
