Abstract

In this paper Lorentz force effect on steady fluid flow and heat transfer of nanofluid is examined. The nanofluid is transported through horizontal parallel plates with magnetic flux of uniform density acting perpendicular to the plates. The effects of thermo-fluidic parameters such as Schmidt number, viscosity and magnetic parameter on flow and heat transfer are presented. Other important heat and mass transfer parameters such as Nusselt and Sherwood numbers practically relevant were also studied. Obtained results from analytical solutions shows quantitative increase of Magnetic parameter varied within the range of 1-4 depicts increasing temperature distribution. Also results when compared with past literatures forms good agreement. Therefore study provides a good emphasis for the advancements of Nano fluidics such as micro mixing, friction reduction, energy conservation, and biological samples.

Highlights

The transport of fluid through parallel surfaces has become increasingly high in most industrial and manufacturing applications today such as power transmission, polymer processing and heat exchangers
Mixed convection of nanofluid flow through square cavities where analyzed by Garoosi et al [4,5] under two phase simulation without and with external heating where results show the effect of buoyancy on cavity flow
Motivated by past research works, the homtopy pertubation method (HPM) is used to investigate Lorentz force effect which is a resistive magnetic force type on steady nanofluid flow and heat transfer coneyed through horizontal parallel plates

Summary

Introduction

The transport of fluid through parallel surfaces has become increasingly high in most industrial and manufacturing applications today such as power transmission, polymer processing and heat exchangers. Convective surface boundary condition was used by Shehzad et al [11] to study three dimensional flow of Jeffery fluid presenting velocity and temperature distribution using series solutions obtained from non-linear equations.
