Effect of particles shape on magnetohydrodynamics hybrid nanofluid flow
and heat transfer in porous medium with slip condition
Abstract
The objective of the present article is to analyze the
magnetohydrodynamic hybrid nanofluid flow and heat transfer in a porous
medium with the nanoparticles shape effect. The effect of thermal
conductivity variation, slip condition and heat generation is also
considered. The Sphere (spherical) and Lamina (non-spherical) shapes of
Al2O3 and Cu nanoparticle are suspended in pure water to form hybrid
nanofluid. The partial differential equations (PDEs) of motion are
converted into ordinary differential equation (ODEs) by well-known
similarity transformation. The resultant ordinary differential equation
(ODEs) are solved analytically with the help of Homotopy analysis method
(HAM). Furthermore, the coeffects of physical parameters on velocity
profiles, temperature profiles and Nusselt number are also taken into
consideration. It is found that the performance of the Lamina
(non-spherical) shapes nanoparticles on temperature disturbance and heat
transfer is better than Sphere (spherical) shape nanoparticles Keywords:
