An efficient hybrid approach for simulating MHD nanofluid flow over a permeable stretching sheet

Abstract

The problem of magnetohydrodynamics boundary layer flow and heat transfer on a permeable stretching surface in a nanofluid under the effect of heat generation and partial slip is simulated using numeric symbolic approach. The Brownian motion and thermophoresis effects are also considered. The boundary layer equations governed by the PDEs are transformed into a set of ODEs with the help of transformations. The differential equations are solved by variational finite element method as well as hybrid approach. The results obtained by the two approaches match well. The effects of different controlling parameters on the flow field and heat transfer characteristics are examined. The comparison confirms excellent agreement. The efficiency of the hybrid approach is demonstrated through a table. The present study is of great interest in coating and suspensions, cooling of metallic plate, oils and grease, paper production, coal water or coal-oil slurries, heat exchangers technology, materials processing exploiting. © Springer India 2015.
