【 摘 要 】

The unsteady magnetohydrodynamic (MHD) mass transfer flow of an incompressible, electrically conducting nanofluid past a porous stretching sheet has been considered. In this study we considered three different types of water based nanofluids viz., copper (Cu), aluminum oxide Al2O3, and titanium dioxide (TiO2). By using appropriate similarity transformations, the governing partial differential equations of momentum and concentration are converted into a set of non-linear ordinary differential equations. The resulting equations are then solved numerically by using shooting method along with R-K fourth order scheme. The effects of diverse flow physical parameters on the flow fields and mass transfer are illustrated graphically. It is found that the influence of unsteady parameter on skin friction coefficient and Sherwood number is opposite.
