Abstract
This comparative study inspects the heat transfer characteristics of magnetohydrodynamic (MHD) nanofluid flow. The model employed is a two-phase fluid flow model. Water is utilized as the base fluid, and zinc and titanium oxide (Zn and TiO2) are used as two different types of nanoparticles. The rotation of nanofluid is considered along the z-axis, with velocity ω*. A similarity transformation is used to transform the leading structure of partial differential equations to ordinary differential equations. By using a powerful mathematical BVP-4C technique, numerical results are obtained. This study aims to describe the possessions of different constraints on temperature and velocity for rotating nanofluid with a magnetic effect. The outcomes for the rotating nanofluid flow and heat transference properties for both types of nanoparticles are highlighted with the help of graphs and tables. The impact of physical concentrations such as heat transference rates and coefficients of skin friction are examined. It is noted that rotation increases the heat flux and decreases skin friction. In this comparative study, Zn-water nanofluid was demonstrated to be a worthy heat transporter as compared to TiO2-water nanofluid.
Highlights
Problems of flow prompted by linear extending surfaces moving with definite velocity often occur in a large range of manufacturing processes
The tabulated datasets for both sets of nanofluids were generated under distinct study parameters, for the local skin friction coefficient and the heat transfer coefficient
Two nanofluid combinations were considered in order to observe and compare the enhanced heat transfer and reduction in skin friction for both cases
Summary
Problems of flow prompted by linear extending surfaces moving with definite velocity often occur in a large range of manufacturing processes. These types of flows have many applications in various assembling processes, such as extrusion of polymers from a dye, processing of foods, chemical fluids, etc. Crane [1] was the first to inspect the basic phenomenon of flow over the linear extending surface. After that, this area of research was found to be very interesting, and researchers began studying it under different physical constraints. Nazar et al [8] promoted unstable flow problems
