Abstract

The main purpose of this research is to scrutinize the heat and mass transfer in the Casson hybrid nanofluid flow over an extending cylinder in the presence of a magnetic dipole and double stratification. The nanofluid contained chemically reactive hybrid nanoparticles (Ag, MgO) in the conventional fluids (water). The effects of viscous dissipation, radiation, and concentration stratification were taken into consideration. In the presence of gyrotactic microorganisms and the Non-Ficks Model, the flow was induced. Incorporating microorganisms into a hybrid nanofluid flow is thought to help stabilize the dispersed nanoparticles. For viscosity and thermal conductivity, experimental relations with related dependence on nanoparticle concentration were used. To acquire the nonlinear model from the boundary layer set of equations, suitable similarity transformations were employed. The built-in function bvp4c of Matlab software was utilized to solve the transformed equation numerically. The graphical results were obtained for temperature, velocity, concentration, and microorganism distribution for various parameters. The numerical amounts of drag friction, heat transport rate, and motile density number for different parameters are presented through tables. It is seen that the fluid velocity is augmented by the increase of the curvature parameter, while a decrease occurs in the fluid velocity with an increase in the magnetic and slips parameters. The comparison of the present study with previously available studies is discussed, which shows a good agreement with published results.

Highlights

A special type of nanofluid called a ferromagnetic nanofluid can be found in electrical and mechanical devices such as shafts and rotating rods, speaker systems, computer hard drives, and rotational X-ray tubes
Concluding Remarks The consideration of two-dimensional radiative Casson fluid flow with a magnetic dipole and microorganisms is presented in the article
The mass and heat transport analyses are observed under the influence of viscous dissipation and generalized Fick’s law

Summary

Introduction

A special type of nanofluid called a ferromagnetic nanofluid can be found in electrical and mechanical devices such as shafts and rotating rods, speaker systems, computer hard drives, and rotational X-ray tubes. NASA originally developed these fluids to control and stabilize fluid motion in space These liquids play an important role in electrochemical and chemical devices. Kumar et al [7] explored the twodimensional Maxwell nanofluid flow implanted with single-wall carbon nanotubes and multiwall carbon nanotubes (SWCNT/MWCNT) across an extending sheet with the impact of radiation and a magnetic dipole. Almaneea [9] numerically studied the improvement of heat transport in a hybrid nanofluid flow when a magnetic dipole was placed atop a sheet embedded in a porous medium. Hayat et al [11] investigated the ferromagnetic Maxwell nanofluid flow over a linearly stretching sheet caused by a magnetic dipole. The flow and heat transport analysis of bio-convective hybrid nanomaterial liquid, with stratification impacts over an extending cylinder, was presented by Khan et al [14]
