Dual Characteristics of Maxwell Hybrid Nanofluid Flow Over a Shrinking Sheet with Variable Heat Source or Sink

Dual Characteristics of Maxwell Hybrid Nanofluid Flow Over a Shrinking Sheet with Variable Heat... Flow and heat transfer of a Maxwell hybrid nanofluid (Cu-Al2O3/water) over a shrinking sheet with effects of magnetic field, suction, and heat source or sink are investigated. The governing equations are transformed into ordinary differential equations using a set of similarity transformations. These equations are solved using the well-established shooting method. Important findings are that the shear stress, heat transfer rate and velocity increase with the increase of Deborah number, buoyancy parameter and suction parameter. The domain of the existence of dual solutions significantly becomes wider with the increase of the suction parameter, Deborah number, magnetic parameter, and volume fraction of Cu nanoparticles. For higher volume fraction of Al2O3 nanoparticles, the shear stress and the rate of heat transfer are found to decrease. Contrary to this, an increase in Cu nanoparticles volume fraction augments the shear stress but reduces the heat transfer rate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Arabian Journal for Science and Engineering Springer Journals

Abstract

Flow and heat transfer of a Maxwell hybrid nanofluid (Cu-Al2O3/water) over a shrinking sheet with effects of magnetic field, suction, and heat source or sink are investigated. The governing equations are transformed into ordinary differential equations using a set of similarity transformations. These equations are solved using the well-established shooting method. Important findings are that the shear stress, heat transfer rate and velocity increase with the increase of Deborah number, buoyancy parameter and suction parameter. The domain of the existence of dual solutions significantly becomes wider with the increase of the suction parameter, Deborah number, magnetic parameter, and volume fraction of Cu nanoparticles. For higher volume fraction of Al2O3 nanoparticles, the shear stress and the rate of heat transfer are found to decrease. Contrary to this, an increase in Cu nanoparticles volume fraction augments the shear stress but reduces the heat transfer rate.
