Analytical approximate solutions for nonplanar Burgers equations by weighted residual method
Demiray, Hilmi; El-Zahar, Essam Roshdy (Elsevier B.V., 2020-08-13)In this work, analytical approximate progressive wave solutions for the generalized form of the nonplanar KdV-Burgers (KdV-B) and mKdV-Burgers (mKdV-B) equations are presented and the results are discussed. Motivated with ... -
Analytical solutions of cylindrical and spherical dust ion-acoustic solitary waves
El-Zahar, Essam Roshdy; Demiray, Hilmi (Elsevier B.V., 2019-06)In the present work, employing the conventional reductive perturbation method to the field equations of an unmagnetized dusty plasma consisting of inertial ions, Boltzmann electrons and stationary dust particles in the ... -
Cylindrical and spherical solitary waves in an electron-acoustic plasma with vortex electron distribution
Demiray, Hilmi; El-Zahar, Essam Roshdy (Amer Inst Physics, 2018-04)We consider the nonlinear propagation of electron-acoustic waves in a plasma composed of a cold electron fluid, hot electrons obeying a trapped/vortex-like distribution, and stationary ions. The basic nonlinear equations ... -
On progressive wave solution for non-planar KDV equation in a plasma with q-nonextensive electrons and two oppositely charged ions
Demiray, Hilmi; El-Zahar, Essam Roshdy; Shan, Shaukat Ali (Işık University Press, 2020)In this paper, the ion-acoustic wave is investigated in a plasma with q-nonextensive electrons and two oppositely charged ions with varying masses. These parameters are found to modify the linear dispersion relation and ...
