Numerical analysis of electromagnetic trihybrid nanofluid flow in a convectively heated permeable channel

Abstract

This research aims to examine the tri-hybrid nanofluid flow in a convectively heated permeable channel with the effect of heat generation/absorption. Tri-hybrid nanofluid is formed by suspending three different nanoparticles namely, aluminium oxide (Al2O3), copper (Cu) and nickel (Ni) in the base fluid water (H2O). For stability of the fluid transverse magnetic and electric fields are considered in the fluid model. The aim of this work is to carry out a comparative study for the heat transfer enhancement of base fluid with mono (Al2O3), hybrid (Al2O3+Cu) and ternary (Al2O3+Cu+Ni) nanofluids. This study is implicated in those fields which are dealing with extreme heat or cold conditions, aerospace technology, biosensors, nano-drugs and metal coatings. The boundary layer equations that govern the flow are transformed to dimension-free form by appropriate transformable variables and then solved by using bvp4c program in MATLAB software. It is found that the fluid flow resist by magnetic parameter and assist by electric field, while the thermal profiles rise by enhancing the value of these parameters. Furthermore, numerical outcomes for skin-friction coefficient and Nusselt number are deliberated in graphical form. Thus, it is concluded that, ternary hybrid nanofluid enhances the thermal conductivity of the base fluid more than to traditional or hybrid nanofluid.
