Traveling Wave Solutions for the Foam Drainage Equation and the Enhanced (G'/G)-Expansion Method

In this paper, the enhanced (G'/G)-expansion method is used to assemble the traveling wave solutions involving parameters of the Foam Drainage equation, where G =G(ξ) satisfies a second order linear differential equation. The traveling wave solutions are expressed by the hyperbolic functions and the trigonometric functions. When some arbitrary functions included in these solutions are taken as some special functions, these solutions possess profuse structures. This method is direct, concise elementary and effective and can be used for many other nonlinear evolutions equations.
