Description
Summary:This article discusses the thermal radiation significance on the 2-D laminar MHD boundary layer flow of a nanofluid, as well as the heat transfer associated with the viscous flow across a nonlinear stretching surface. The flow is produced by a nonlinearly enlarging sheet with varying temperatures in the existence of suction, radiation, and viscous dissipation. By applying suitable similarity conversions, the resultant governed PDEs are transformed to a set of nonlinear ODE's, and then, they are solved by applying the Keller-Box approach numerically. The impact of several flow pertinent factors on heat, species concentration, and velocity fields are exposed graphically and numerically. Numerical calculations for friction factor, mass, and heat transmission rates are discussed in table form. Prior results were examined under constraining circumstances and found to be adequate. It is discovered that when the velocity slip factor is enhanced, the fluid velocity distribution declines whereas the heat and concentration gradients increase. The principal results indicate that the porosity parameter effectively decreases the velocity distribution.
