چکیده
In this investigation, the nonplanar (spherical and cylindrical) modified fifth-order Korteweg–de Vries (nmKdV5) equation, otherwise known as Kawahara equation (nmKE), is solved using ansatz approach. Two general formulas for semi-analytical symmetric approximations are derived recommended methodology. Using obtained approximations, (mK) solitary waves (SWs) cnoidal (CWs) obtained. The fluid equations electronegative plasmas reduced to nmKE a practical application solutions. solutions, characteristic features of both cylindrical spherical mK-SWs -CWs studied. All solutions compared with each other, maximum residual errors these estimated. Numerous researchers that interested in studying complicated nonlinear phenomena plasma physics can use interpret their experimental observational findings.

Analytical Soliton Solutions Modeling of Nonlinear Schrödinger Equation with the Dual Power Law Nonlinearity
Introduction In this study, we use a newly proposed method based on the software structure of the maple, called the Khaters method, and will be introducing exponential, hyperbolic, and trigonometric solutions for one of the Schrödinger equations, called the nonlinear Schrödinger equation with the dual power law nonlinearity. Given the widespread use of the Schrödinger equation in physics and e...
متن کاملNonlinear Stability of Solitary Travelling-wave Solutions for the Kawahara-kdv and Modified Kawahara-kdv Equations
In this paper we establish the nonlinear stability of solitary travelling-wave solutions for the Kawahara-KdV equation ut + uux + uxxx − γ1uxxxxx = 0, and the modified Kawahara-KdV equation ut + 3u 2ux + uxxx − γ2uxxxxx = 0, where γi ∈ R is a positive number when i = 1, 2. The main approach used to determine the stability of solitary travelling-waves will be the theory developed by Albert in [1].
متن کاملThe van der Waals equation: analytical and approximate solutions
The thermodynamic properties, enthalpy of vaporization, entropy, Helmholtz function, Gibbs function, but especially the heat capacity at constant volume of a van der Waals gas (and liquid) at the phase transition are examined in two different limit approximations. The first limit approximation is at the near-critical temperatures, i.e., for T/Tc → 1, where Tc is the critical temperature, the ot...
متن کاملNew Approximate Analytical Solutions of the Falkner-Skan Equation
We propose an iterative method for solving the Falkner-Skan equation. The method provides approximate analytical solutions which consist of coefficients of the previous iterate solution. By some examples, we show that the presented method with a small number of iterations is competitive with the existing method such as Adomian decomposition method. Furthermore, to improve the accuracy of the pr...
متن کاملAnalytical solutions for the fractional Fisher's equation
In this paper, we consider the inhomogeneous time-fractional nonlinear Fisher equation with three known boundary conditions. We first apply a modified Homotopy perturbation method for translating the proposed problem to a set of linear problems. Then we use the separation variables method to solve obtained problems. In examples, we illustrate that by right choice of source term in the modified...
