Abstract

In this paper, the researchers explore heat transfer and magneto-hydrodynamic flow of hybrid nanofluid in a rotating system among two surfaces. The upper and lower plates of the system are assumed penetrable and stretchable, respectively. The thermal radiation and Joule heating impacts are considered. A similarity technic is applied to alter governing energy and momentum equations into non-linear ordinary differential ones that contain the convenient boundary conditions and used the Duan-Rach Approach (DRA) to solve them. Influences of assorted parameters including rotation parameter, suction/blowing parameter, radiation parameter, Reynolds number, hybrid nanofluid volume fraction, and magnetic parameter on temperature and velocity profiles are examined. Also, a correlation for the Nusselt number has been developed in terms of the acting parameters of the present study. The outcomes indicate that Nusselt number acts as an ascending function of injection and radiation parameters, as well as volume fraction of nanofluid.

Summary

Introduction

The examination of heat transfer and fluid flow among surfaces is one of the most notable topics of research in recent years owing to the breadth of its engineering and scientific utilizations. Mustafa et al. examined the heat, fluid flow, and mass transfer between two plates. Their outcomes indicate that the augmenting values of the Schmidt number reduces the concentration profile and enhances the local Sherwood number’s magnitude of. Their outcomes illuminate that the Nusselt number rises as the Prandtl number rises. Dogonchi et al. studied heat and flow transfer of magneto-hydrodynamic Graphene oxide/water nanofluid under thermal radiation and among two flat surfaces. They sighted that there is a direct relationship between Nusselt number and temperature profile and solid volume fraction. Alizadeh et al. have studied magneto-hydrodynamic micropolar fluid flow within a channel filled by nanofluid subject to thermal radiation
