Chemical reaction and thermal radiation impact on a nanofluid flow in a rotating channel with Hall current

Abstract

The objective of the present exploration is to examine the nanoliquid flow amid two horizontal infinite plates. The lower plate is stretchable and permeable. The uniqueness of the flow model is assimilated with the Hall effect, variable thermal conductivity, thermal radiation, and irregular heat source/sink. Transmission of mass is enhanced with the impression of chemical reaction incorporated with activation energy. Appropriate similarity transformation is applied to transform the formulated problem into ordinary differential equations (ODEs). The numerical solution is obtained by employing MATLAB software function bvp4c. The dimensionless parameters are graphically illustrated and discussed for the involved profiles. An increasing behavior is exhibited by the temperature field on escalating the Brownian motion, thermophoresis parameter, variable thermal conductivity, and radiation parameter. For larger values of Schmidt number and chemical reaction parameter, the concentration profile deteriorates, while a reverse trend is seen for activation energy. The rate of heat transfer is strengthened at the lower wall on amplifying the Prandtl number. A comparative analysis of the present investigation with already published work is also added to substantiate the envisioned problem.

Computational Assessment of Microrotation and Buoyancy Effects on the Stagnation Point Flow of Carreau–Yasuda Hybrid Nanofluid with Chemical Reaction Past a Convectively Heated Riga Plate

“…In this article, it was predicted that the mass transport of the hybrid nanoliquid is decreased due to the intensifying chemical reaction effect. Lv et al 42 described the consequence of the Hall effect over the nanoliquid flow as a result of a radiation effect through a rotating channel. They discussed that the energy frequency transport is higher for larger evaluations of the Prandtl number.…”

“…Ahmed et al 22 investigated the issue of thermal radiation and heat flux affecting MHD laminar fluid flow when a sheet stretches. Lv et al 23 used a numerical method to study the effect of hall currents on the flow of nanofluids in a rotating channel. Rama Devi and Reddy 24 investigated the effect of entropy generation along with thermal radiation and chemical reaction on hybrid nanofluid due to stretching of the sheet.…”

A Numerical Analysis on MHD Hybrid Nanofluid flow and Heat transfer over a Permeable Stretching Sheet under the Influence of Thermal Radiation

“…Subsequent research by Ali et al [18] studied how thermal radiation made an impact on the MHD hybrid nanofluid flow along the stretching cylinder. In a situation where the bottom plate was permeable and stretchy, Lv et al [19] have investigated the impact of thermal radiation, hall current, and uneven heat source/sink on the flow of nanofluid between two horizontal flat plates. Rao and Deka [20] have considered the effect of thermal radiation and chemical reaction on MHD Casson nanofluid flow caused due to a stretching sheet.…”
