Buongiorno s model for unsteady convective boundary layer flow of a nanofluid along a permeable shrinking/stretching sheet in presence of second-order slip

In this article. the influence of second—order slip on unsteady convective boundary layer [low of a Buongiomo‘s nanolluid (in which nanoparticlcs Brownian motion and thermophoresis effects are taken into account) along a permeable shrinking/stretching plate in the presence of suction has been investigated. The similarity solution is used to reduce the governing, system of partial differential equations to a set of nonlinear ordinary differential equations which are then solved numerically by the Keller-box method (KBM). The results are presented in graphical form illustrating the effects of model parameters on boundary layer behavior. Moreover. these outcomes are supplemented with the data for the skin friction and the reduced Nusselt number. It is found that dual solutions exist for a shrinking plate, and the range of the shrinking parameter for which the solution exists, increases with the slip parameters. Finally. the analysis for no-slip and first-order slip boundary conditions can also be retrieved as special cases of the present model.
