Unsteady flow of Heat and Mass transfer in Viscoelastic fluid over a stretching sheet with the effect of chemical reaction

An analysis has been made to study the heat and mass transfer of an unsteady flow of a viscoelastic fluid over a stretching sheet in the presence of chemical reaction and suction parameter. The basic governing equations of the flow which are in the form of partial differential equations have been reduced to non linear ordinary differential equations by applying similarity transformations. The transformed equations are further solved by employing Runge-Kutta fourth order method along with shooting technique, Numerical results for velocity, heat and mass transfer rate are discussed graphically for different parameters.
