Energy and mass transport through hybrid nanofluid flow passing over an extended cylinder with the magnetic dipole using a computational approach

Abstract

The objective of this research is to evaluate the heat and mass transfer in a water-based Darcy–Forchheimer hybrid nanofluid (HNF) flow across an expanding cylinder. The fluid flow has been studied under the influence of a magnetic field, viscous dissipation, heat source, thermal radiation, concentration stratification, and chemical reaction. Carbon nanotubes (CNTs) and iron ferrite (Fe3O4) nanoparticles (NPs) are added to the water, for the purpose of synthesizing the HNF. The fluid flow has been induced in the presence of gyrotactic microorganisms and the non-Fick’s model. Microorganisms are used to stabilize scattered nanoparticles through the hybrid nanofluid. The phenomena have been modeled in the form of a nonlinear system of partial differential equations (PDEs). The modeled equations are reduced to a dimensionless system of ODEs by using similarity substitution. The numerical solution of the derived sets of nonlinear differential equations is obtained by using the parametric continuation method. The impact of physical constraints on temperature, velocity, concentration, and microorganism profiles is presented through figures and tables. It has been observed that the heat and mass transport rates increase with the rising effect of the curvature parameter, while declining with the effect of the thermal stratification parameter.

Flow and heat transfer in a meandering channel

“…In (Taylor, 1923), it was found that the special type of instability is prominent for fluid flow over concave and convex sheets, subject to the condition that the velocity components are non-monotonic in nature. In (Ghalambaz et al, 2016;Hayat et al, 2017;Srinivasacharya and Sibanda, 2020;Mahmud and Uddin, 2021), numerical simulation and analysis of different types of nanofluids flowing past various types of surfaces in the context of fluid flow and heat transfer in different channels was performed (Khan and Ahmed, 2015;Alsaedi et al, 2016;Nadeem et al, 2016;Izadi and Pourmehran, 2017;Khan et al, 2017;Sheikholeslami et al, 2017). These studies explore the impact of various factors such as thermal radiation, magnetic fields, bioconvection, entropy optimization, and chemical reactions on flow and heat transfer characteristics.…”

Tangent Hyperbolic Fluid Flow under Condition of Divergent Channel in the Presence of Porous Medium with Suction/Blowing and Heat Source: Emergence of the Boundary Layer

“…In the context of radiative stagnation point fow of nanofuid with cross-difusion and viscous dissipation, Qaiser et al [23] illustrated the relevance of entropy optimization and activation energy. Using a computational technique, Khan et al [24] explored the movement of mass and energy in a hybrid nanofuid fowing across an extended cylinder containing a magnetic dipole. Nonlinear radiative nanofuidic hydrothermal unsteady bidirectional transport with thermal/mass convection issues was researched by Faisal et al [25].…”
