Numerical solutions of coupled Burgers equations with time- and space-fractional derivatives

In this paper, by introducing the fractional derivative in the sense of Caputo, the Adomian decomposition method is directly extended to study the coupled Burgers equations with time- and space-fractional derivatives. As a result, the realistic numerical solutions are obtained in a form of rapidly convergent series with easily computable components. The figures show the effectiveness and good accuracy of the proposed method. (C) 2007 Elsevier Inc. All rights reserved.
