Abstract

ABSTRACT

The Burgers Korteweg-de Vries equations have widely applications in fluid mechanics, physics and engineering. By assume that the solutions of the KdVB equation are be able to presented as the sum of some periodic waves, the solutions of the KdVB can be transformed into spectral space. In this paper, the numerical solutions of the KdVB equation by using spectral methods are discussed. By using FFT and IFFT syntax the KdVB equation solved numerically. By using this solution we investigate that if the dissipative coefficient going smaller then the solitary wave will be dispersed.
