Abstract
AbstractThis paper considers the problem of steady, boundary layer flow and heat transfer of a nanofluid with fluid-particle suspension over an exponentially stretching surface in the presence of transverse magnetic field and viscous dissipation. The stretching velocity and wall temperature are assumed to vary according to specific exponential form. The governing equations in partial forms are reduced to a system of coupled non-linear ordinary differential equations using suitable similarity transformations. An effective Runge–Kutta–Fehlberg (RKF-45) is used to solve the obtained differential equations with the help of a symbolic software MAPLE. The effects of flow parameters—such as nanofluid interaction parameter, magnetic parameter, solid volume fraction of nanoparticle parameter, Prandtl number and Eckert number—on the flow field and heat-transfer characteristics were obtained and are tabulated. Useful discussions were carried out with the help of plotted graphs and tables. Under the limiting cases, c...

Summary
During the past few decades, the study of boundary layer flow and heat transfer over a stretching surface has achieved a lot of success because of its large number of applications in industry and technology. The concept of nanofluid was first introduced by Choi (1995) in the article enhancing thermal conductivity of fluids with nanoparticles Based on this pioneer work, Mabood, Khan, and Ismail (2015a, 2015b) focused on the study of combined heat and mass transfer of electrically conducting nanofluid over a non-linear stretching surface in the presence of a first-order chemical reaction and viscous dissipation. They (Mabood & Khan, 2014) have obtained the series solution for MHD stagnation point flow in porous medium for different values of Prandtl number and suction/injection parameter. Heat-transfer phenomenon are solved for two types of heating process, namely, Prescribed exponential-order surface temperature (PEST) and Prescribed exponential-order heat flux (PEHF)
