Numerical simulation and solutions of the two‐component second order KdV evolutionarysystem

Abstract: In this study, with the aid of Wolfram Mathematica 11, the modified exp (− (η))-expansion function method is used in constructing some new analytical solutions with novel structure such as the trigonometric and hyperbolic function solutions to the well-known nonlinear evolutionary equation, namely; the two-component second order KdV evolutionary system. Second, the finite forward difference method is used in analyzing the numerical behavior of this equation. We consider equation (6.5) and (6.6) for the numeric… Show more

“…The first example presents that the convergence order of difference Scheme (2.23)–(2.27) is O( τ 2 + h 2 ).Example In (1.1)–(1.5), let L = 1, T = 1. In order to test the convergence rate of the proposed method, we consider the exact solution of the problem (1.1)–(1.5) as follows . ux,t=x2()x12et,vx,t=t2sinπx, which determine f()x,t=x2x12et3π2t2normalsin()πitalicx,g()x,t=2tnormalsin()πitalicx[]2x12et+8x()x1et+2x2et4xx14e2t,ϕ()x=x2x12,0.6emψ()x=0. …”

“…Some numerical examples are provided. In , the forward finite difference method was used in analyzing the numerical behavior of the two‐component second‐order KdV evolutionary system, the stability of this scheme was analyzed by using the Fourier‐Von Neumann analysis. The accuracy of this difference scheme was checked in L 2 and L ∞ norm.…”

“…The mathematical groundwork for derivatives of fractional order was laid through combined efforts of pioneers such are Liouville, Riemann, Caputo, Miller and Ross, Podlubny, and others. The theory of fractional‐order calculus has been related to practical projects, and it has been applied to chaos theory, signal processing, electrodynamics, fluid dynamics, finance, and other areas …”

[13][14][15][16][17][18][19][20][21][22][23] The Burgers equations are the fundamental nonlinear partial differential equations that exist in distinct connected branches of science and technology. These equations can be seen as a simplified model of fluid dynamics, and it is used as a computational tool in order to deal with more complex problems.…”
