This paper investigates the heat transfer performance of magnetohydrodynamic hybrid nanofluid on a stretching inclined surface. The study shows that using Al2O3-Cu/water hybrid nanofluid can enhance the heat transfer rate compared to simple Cu/water nanofluid.
In this paper, magnetohydrodynamic hybrid nanofluid is considered to study the heat transfer performance due to stretching of inclined surface. The stretching surface is considered under the effects of magnetic field along the normal direction. The surface is inclined such that it makes an angle of 45(0) with x - axis. The working nanofluid is composed of water and fraction of Al2O3 and Cu nanoparticles. The flow is generated due to stretching of surface with constant velocity. Set of nonlinear partial differential equations, including continuity, momentum and energy equations, governs the flow and heat transfer. Similarity transformation technique is applied to convert them to nondimensional form. Transformation gives rise to number of physical parameters, such as Eckert number, suction parameter, convective parameter, and magnetic parameter. The numerical solution is sought using Picard Chelyshkov polynomial method, to evaluate the flow and heat transfer phenomenon against the range of emerging physical parameter. The study revealed that, in comparison with the simple Cu/water nanofluid, heat transfer rate is augmented utilizing Al2O3-Cu/water hybrid nanofluid.
