MHD Micropolar Nanofluid Flow over an Exponentially Stretching/Shrinking Surface: Triple Solutions

Abstract

In this study, the problem of MHD micropolar nanofluid boundary layer flows over an exponentially stretching/shrinking sheet with radiation and suctioneffect is considered. The Buongiorno’s nanofluid model is applied tothe problem. The governing equations arefirsttransformed to the coupled nonlinear similarity equations by using similarity transformations. The resulting equations which isin ordinary differential equations form arethen solved numerically by using shooting method. Triple solutions are observed to exist for the flows.A comparison with existing solutions in literature for specific case are made to assess the accuracy of the present results. Further, the flows profiles are examined,and it is found thatthe presence of suction parameter will contribute the occurrences of triple solutions.
