Dust Ion Acoustic Solitary Waves In Plasma With Cairns Distributed Electrons And New Classical Distribution Of Ions

View through CrossRef
In this composition of plasma with negative dust charge, new classical distribution of nonthermal ions and Cairns distributed electrons, both supersonic and subsonic only rarefactive solitons are found to exist. It appears to conclude that the solitons cease to exist at the increase of c. The supersonic (M = 1.4) rarefactive solitons considerably and concavely increase from small amplitude with the increase of the ion to dust density ratio Q for various values of temperature  . The concave but increasing growth of amplitude of the rarefactive solitons for all M (>1) exhibits its distinct character. Smaller the Mach number (e.g., for M = 1.2), smaller is the amplitude of the solitons throughout the range of 0 (ion drift). The amplitudes of the rarefactive supersonic solitons are found to increase at the increase of the non-thermal parameter  for all r ( 0 0 / e i n n ). The dynamical scenario of this model indicates that the mass of the dusts should decrease in the plasma to generate higher amplitude solitons. В плазме с отрицательным пылевым зарядом с новым классическим распределением нетепловых ионов и электронов с распределением Кэрнса, как сверхзвуковых, так и дозвуковых, существуют только разреженные солитоны. По-видимому, можно сделать вывод, что солитоны перестают существовать при увеличении c. Сверхзвуковые (M = 1.4) разреженные солитоны с малой амплитудой значительно и полого увеличиваются с ростом отношения плотности ионов к плотности пыли Q для различных температур  . Пологый рост амплитуды разреженных солитонов для всех M (>1) имеет свой отчетливый характер. Чем меньше число Маха (например, при М=1.2), тем меньше амплитуда солитонов во всем диапазоне 0 (дрейф ионов). Обнаружено, что амплитуды разреженных сверхзвуковых солитонов растут с увеличением нетеплового параметра  для всех r (  ne0 ni0 ). Динамический сценарий этой модели указывает на то, что масса пыли должна уменьшаться в плазме для генерации солитонов более высокой амплитуды.

Description:
In this composition of plasma with negative dust charge, new classical distribution of nonthermal ions and Cairns distributed electrons, both supersonic and subsonic only rarefactive solitons are found to exist.

The supersonic (M = 1.
4) rarefactive solitons considerably and concavely increase from small amplitude with the increase of the ion to dust density ratio Q for various values of temperature  .
The concave but increasing growth of amplitude of the rarefactive solitons for all M (>1) exhibits its distinct character.
Smaller the Mach number (e.

, for M = 1.
2), smaller is the amplitude of the solitons throughout the range of 0 (ion drift).
The amplitudes of the rarefactive supersonic solitons are found to increase at the increase of the non-thermal parameter  for all r ( 0 0 / e i n n ).
The dynamical scenario of this model indicates that the mass of the dusts should decrease in the plasma to generate higher amplitude solitons.
