  • nonlinear korteweg de vries Burger Equation for ion acoustic shock waves in the presence of kappa distributed electrons and positrons
    Plasma Physics and Controlled Fusion, 2011
    Co-Authors: Asif Shah, R Saeed

    Abstract:

    The ion-acoustic shock waves are studied in electron–positron–ion plasma. The plasma system is composed of three components, specifically relativistic adiabatic ions, kappa distributed electrons and positrons. The Korteweg–de Vries–Burger Equation is derived, solved analytically. The effects of plasma parameters on the shock strength and steepness are investigated. The numerical results are presented graphically for illustration. The results may have importance in non-thermal and relativistic plasmas of pulsar magnetosphere (Arons 2009 Astrophys. Space Sci. Library 357 373; Blasi and Amato arXiv:1007.4745V1 [astro-Ph.HE]).

  • nonlinear korteweg de vries Burger Equation for ion acoustic shock waves in a weakly relativistic electron positron ion plasma with thermal ions
    Physics of Plasmas, 2010
    Co-Authors: R Saeed, Asif Shah

    Abstract:

    The nonlinear propagation of ion acoustic waves in electron-positron-ion plasma comprising of Boltzmannian electrons, positrons, and relativistic thermal ions has been examined. The Korteweg–de Vries–Burger Equation has been derived by reductive perturbation technique, and its shock like solution is determined analytically through tangent hyperbolic method. The effect of various plasma parameters on strength and structure of shock wave is investigated. The pert graphical view of the results has been presented for illustration. It is observed that strength and steepness of the shock wave enervate with an increase in the ion temperature, relativistic streaming factor, positron concentrations, electron temperature and they accrue with an increase in coefficient of kinematic viscosity. The convective, dispersive, and dissipative properties of the plasma are also discussed. It is determined that the electron temperature has remarkable influence on the propagation and structure of nonlinear wave in such relativ…

  • analytical solution for the time fractional bbm Burger Equation by using modified residual power series method
    Complexity, 2018
    Co-Authors: Jianke Zhang, Longquan Yong, Yuelei Xiao

    Abstract:

    In this study, a generalized Taylor series formula together with residual error function, which is named the residual power series method (RPSM), is used for finding the series solution of the time fractional Benjamin-Bona-Mahony-Burger (BBM-Burger) Equation. The BBM-Burger Equation is useful in describing approximately the unidirectional propagation of long waves in certain nonlinear dispersive systems. The numerical solution of the BBM-Burger Equation is calculated by Maple. The numerical results show that the RPSM is reliable and powerful in solving the numerical solutions of the BBM-Burger Equation compared with the exact solutions as well as the solutions obtained by homotopy analysis transform method through different graphical representations and tables.
