Numerical analysis of Ag–CuO/water rotating hybrid nanofluid with heat generation and absorption

Abstract

The present work is committed to examining the impacts of magnetohydrodynamics (MHD), heat generation–absorption, and volume fraction of nanoparticles on the flow of hybrid nanofluid past a stretching surface. The comparison of heat transfer properties of rotating, conventional nanofluid with that of developing hybrid nanofluid is also studied. To examine the Lorentz force impacts on three-dimensional stretching surface, another model of “thermophysical properties” is used. The whole system, including nanofluid and stretching surface, is in rigid body rotation about an axis normal to the plane of the stretching surface with constant angular velocity. The system of governing nonlinear partial differential equations has been simplified by using suitable similarity transformations and then solved via an efficient numerical technique, BVP-4C. The velocity and local skin friction are obtained in both directions. The rate of heat transfer is determined on the surface. The effects of pertinent physical parameters, which are magnetic parameter, rotation parameter, stretching parameter, heat generation or absorption parameter, and Prandtl number, have been discussed through graphical and tabular form. From the present study, it is noticed that the rate of heat transfer of hybrid nanofluid is higher than that of ordinary nanofluid. In hybrid nanofluid, the required rate of heat transfer can be accomplished by picking distinctive and suitable nanoparticle extents.
