diffusion of chemically reactive species in stagnation-point flow of a third grade fluid: a hybrid numerical method

The boundary layer flow of a third grade fluid and mass transfer near a stagnation-point with diffusion of chemically reacting species on a porous plate is investigated. due to a porous plate the suction is taken into an account. using suitable transformations, the momentum and concentration equations are first transformed into nonlinear ordinary ones and then solved using a hybrid numerical method. this method combines the features of finite difference and shooting methods. the effects of various controlling parameters on the flow velocity, concentration profile, skin friction and rate of mass transfer on surface are analyzed graphically and in tabular form. comparison of the present results with the previous reported results has been found in excellent agreement.
