Boundary-Layer Flow of Nanofluids over a Moving Surface in the Presence of Thermal Radiation, Viscous Dissipation and Chemical Reaction

The flow problem presented in the paper is boundary-layer flow of nanofluids over a moving surface in the presence of thermal radiation, viscous dissipation and chemical reaction. The plate is assumed to move in the same or opposite direction to the free stream which depends on the sign of the velocity parameter. The partial differential equations appearing in the governing equations are transformed into a couple of nonlinear ordinary differential equations using similarity transformations. The transformed equations in turn are solved numerically by the shooting method along with the fourth order RungeKutta integration technique. Influences of the pertinent parameters in the flow field are exhaustively studied and sequentially explained graphically and in tabular form. For selected values of the parameters involved in the governing equations like Lewis number, the velocity parameter, magnetic parameter, Eckert number Brownian motion parameter, thermophoresis parameter, thermal radiation parameter, Prandtl number, Reynolds number and chemical reaction parameter, numerical results for the velocity field, temperature distribution, concentration, skin friction coefficient, Nusselt number and Sherwood number are obtained. The results are analyzed and compared with previously published works; they are found in excellent agreement.
