Dual approximate solutions for the chemically reactive solute transfer in a viscous fluid flow.

The flow as well as the chemically reactive solute transfer problem in a viscous fluid over an exponentially stretching sheet are analytically investigated in this work. The nonlinear differential equations associated to the motion equations are approximately solved by means of the modified Optimal Homotopy Asymptotic Method (OHAM). The dual approximate analytical solutions are obtained. By comparison with the corresponding numerical solutions a good agreement is performed and show that this procedure is effective, accurate and easy to use in applications. [ABSTRACT FROM AUTHOR]
