“…The above results in (8) and (9) are comparable with the results of Shah and Saeed (2009) for relativistic plasma with the Boltzmann distribution of electrons. Equation (8) is the well known KdV Burger equation describing the nonlinear propagation of the ion acoustic shock waves in a plasma with superthermal electrons.…”

“…They showed that the positron concentration, ratio of ion to electron temperature, and the plasma kinematic viscosity significantly modifies the shock structure. More recently, Shah and Saeed (2009) have derived the Kortewegde Vries-Burger (KdVB) equation ion acoustic shock waves in a weakly relativistic electron-positron-ion plasma. They found that the amplitude and steepness of the shock wave decrease with increase of the relativistic streaming factor and the positron concentration.…”

Ion acoustic shock waves (IASWs) are studied in a plasma consisting of electrons, positrons and ions. Boltzmann distributed positrons and superthermal electrons are considered in the plasma. The dissipation is taken into account the kinematic viscosity among the plasma constituents. The Korteweg-de Vries-Burgers (KdV-Burgers) equation is derived by reductive perturbation method. Shock waves are solutions of KdV-Burgers equation. It is observed that an increasing positron concentration decreases the amplitude of the waves. Furthermore, in the existence of the kinematic viscosity among the plasma, the shock wave structure appears. The effects of ion kinematic viscosity (η 0 ) and the superthermal parameter (k) on the ion acoustic waves are found.

“…This result congruent with the one made by Masood et al (2009) in e-p-i plasma consisting adiabatically hot positive ions and by Masood et al (2008) in quantum e-p-i plasmas. This result also is in agreement with the result of Shah et al (2009) for e-p-i plasma with the Boltzmann distribution of electron.…”

“…Ion-acoustic shock waves were first observed in a novel plasma device called Double Plasma device (Taylor et al 1970a). Asif Shah et al (2009) have derived the Korteweg-de Vries-Burger (KdVB) equation ion acoustic shock waves in a weakly relativistic electron-positron-ion plasma. During the last two decades, Space plasma observations indicate clearly the presence of electron populations which are far away from their thermodynamic equilibrium.…”

Effect of q-nonextensive distribution of electrons on ion acoustic shock waves in dissipative plasma

Ion acoustic shock waves (IASWs) are studied in a plasma consisting of nonextensive electrons and ions. The dissipation is taken into account the kinematic viscosity among the plasma constituents. The Korteweg-de VriesBurgers (KdV-Burgers) equation is derived by reductive perturbation method. Shock waves are solutions of KdVBurgers equation. It is shown that acceptable values of q-parameter (where q stands for the electron nonextensive parameter) are more than 3 in a weakly nonlinear analysis. We have found that the amplitude of shock waves decreases by an increasing q-parameter.

Dissipative ion‐acoustic waves in collisional electron‐positron‐ion plasmas with Kappa distribution

In this work, linear and non-linear structures of ion-acoustic waves (IAWs) are investigated in a collisional plasma consisting of warm ions, superthermal electrons, and positrons. A dissipative effect is assumed due to ion-neutral collisions. The linear properties of IAWs are investigated. It is shown that the dynamics of the IAWs is governed by the damped Korteweg-de Vries (K-dV) equation. It is seen that the ion-neutral collisions modify the basic features of ion-acoustic solitary waves significantly. Also, the effect of the plasma parameters on the dissipative IAWs is discussed in detail.
