Unsteady natural convective boundary-layer flow of MHD nanofluid over a stretching surfaces with chemical reaction using the spectral relaxation method: A revised model

We investigate heat and mass transfer in an unsteady MHD nanofluid boundary layer flow due to a stretching surface. The traditional model which here includes the effects of Brownian motion and thermophoresis is revised, so that the nanofluid particle volume fraction on the boundary is passively rather than actively controlled. In this respect the problem is more realistic. This problem is modeled using systems of nonlinear partial differential equations which have been solved numerically using the spectral relaxation method. The results are benchmarked with previously published results. (C) 2015 The Authors. Published by Elsevier Ltd.
