Numerical Investigation of Non-Newtonian Williamson Hybrid Ferrofluid Flow over a Stretching Sheet: Effects of Magnetic, Stretching and Thermal Parameters

Abstract

Non-Newtonian Williamson fluid has become the topic of interest among researchers due to shear thinning properties that can represent real life applications. Hybrid ferrofluid are also considered because of its higher heat transfer rather than a single domain ferrofluid. This research aims to discover the flow of non-Newtonian Williamson hybrid ferrofluid along the stretching sheet. Partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) by using similarity transform variable. The transformed ODEs are solved numerically by using mathematical algorithm encoded in Maple software. The effect of velocity and temperature profiles are discussed for several parameters such as magnetic parameter, stretching parameter, non-Newtonian Williamson fluid parameter, Prandtl number and local Eckert number. It is discovered that the velocity profile increases as the value of magnetic and stretching parameter are increased. On the other hand, the temperature profile increases due to increasing magnetite and copper nanoparticles volume fraction, stretching parameter, non-Newtonian fluid parameter and Eckert number.
