Abstract.

In this paper, we develop an accurate and efficient natural transform homotopy per- turbation method for obtaining the numerical solution of nonlinear fractional Newell-Whitehead- Segel equation arise in various physical phenomena such as fluid mechanics, solid-state physics, optics, plasma physics, dispersion and chemical kinetics. We apply natural transform coupled with the homotopy perturbation method to bring down the nonlinear terms for obtaining the approximate solution.
