Abstract

Ferroliquids are an example of a colloidal suspension of magnetic nanomaterials and regular liquids. These fluids have numerous applications in medical science such as cell separation, targeting of drugs, magnetic resonance imaging, etc. The hybrid nanofluid is composed by scattering the magnetic nanomaterial of more than one type nanoparticles suspended into the base fluid. It has different scientific applications such as heat dissipation, dynamic sealing, damping, etc. Owing to the vast ferrofluid applications, the time-dependent squeezed flow of hybrid ferroliquids under the impact of non-linear radiation and mixed convection within two disks was explored for the first time in this analysis. Here, the cobalt and magnetite ferrofluids are considered and scattered in a 50%:50% mixture of water–EG (ethylene glycol). The similarity technique is used to reduce the leading PDEs into coupled non-linear ODEs. The transmuted equations together with recommended boundary restrictions are numerically solved via Matlab solver bvp4c. The opposing and assisting flows are considered. The impacts of an emerging parameter on fluid velocity and temperature field of hybrid ferroliquids are examined through the different graphical aids. The results showed that the opposite trend is scrutinized due to the magnetic influence on the temperature and velocity in the case of assisting and opposing flows. The velocity augments due to the volume fraction of nanoparticles in the assisting flow and declines in the opposing flow, while the opposite direction is noticed in the temperature field.

Highlights

  • The time-dependent squeezed flow is regularly addressed in realistic surroundings to describe the movement of fluid along an area of contracting of a recommended length

  • The magnetic function on squeezing flow connecting two analogous permeable disks was inspected by Hayat et al (2012a)

  • The friction factor and heat transport rate decline owing to M in the assisting flow and augment in the opposing flow

Summary

Introduction

The time-dependent squeezed flow is regularly addressed in realistic surroundings to describe the movement of fluid along an area of contracting of a recommended length. This flow can be set up via placing a preliminary sluggish liquid between a couple of rectangular parallel disks and plates to indicate the related mathematical models on specific planes of coordinates. Domairry and Aziz (2009) applied the magnetic function on squeezing flow between two disks. The magnetic function on squeezing flow connecting two analogous permeable disks was inspected by Hayat et al (2012a). The impact of imposed magnetic forces on squeezed flow containing nanomaterials between two plates was examined by Babazadeh et al (2020)
