Analytical approximate solutions of fractionel convection-diffusion equation with modified Riemann-Liouville derivative by means of fractional variational iteration method

Abstract

In this article, an analytical approximate solution of nonlinear fractional convection-diffusion with modifiedRiemann-Liouville derivative was obtained with the help of fractional variational iteration method (FVIM). A newapplication of fractional variational iteration method (FVIM) was extended to derive analytical solutions in theform of a series for this equation. It is indicated that the solutions obtained by the FVIM are reliable and aneffective method for strongly nonlinear partial equations with modified Riemann-Liouville derivative.
