Numerical approach towards gyrotactic microorganisms hybrid nanoliquid flow with the hall current and magnetic field over a spinning disk

Abstract

The article explores the effect of Hall current, thermal radiation, and magnetic field on hybrid nanofluid flow over the surface of a spinning disk. The motive of the present effort is to upgrade the heat transmission rate for engineering and industrial purposes. The hybrid nanofluids as compared to the conventional fluids have higher thermal properties. Therefore, in the present article, a special class of nanoparticles known as carbon nanotubes (CNTs) and iron ferrite nanoparticles are used in the base fluid. The system of modeled equations is depleted into dimensionless differential equations through similarity transformation. The transform equations are further solved through the Parametric Continuation method (PCM). For the parametric study, the physical parameters impact on velocity, energy, mass transmission, and motile microorganism’s concentration profiles have been sketched. The obtained results are compared with the existing literature, which shows the best settlement. It concluded that the heat transmission rate reduces for Hall current and rises with radiative parameter. The results perceived that the addition of CNTs in carrier fluid is more efficacious than any other types of nanoparticles, due to its C–C bond. CNTs nanofluid can be more functionalized for the desired achievement, which can be utilized for a variety of applications by functionalization of non-covalent and covalent modification.

“…An alkaline coprecipitation procedure was used to create magnetic nanoparticles with a basic crystal structure of 9 nm, which were subsequently coated with sulfate. A study conducted by Bilal et al 33 considered the impacts of Hall current on the flow of carbon nanotubes and iron ferrite hybrid nanoliquids along the surface of a spinning disc.…”

Mixed convection and thermally radiative hybrid nanofluid flow over a curved surface

“…Through non-covalent and covalent modification, CNTs NF may be further derivatized to obtain the desired outcome, which can then be employed in a variety of functions. 14 Employing fluid flow across a curved surface, Saeed et al 6 investigated the hybrid NF using CNTs and iron oxide nanoparticles. Inside a square cavity, Sreedevi and Sudarsana Reddy 15 and Sreedevi and Reddy 16 performed a statistical analysis of energy transfer, flow, and entropy generating aspects of a hybrid NF.…”
