A Numerical Approach for the Heat Transfer Flow of Carboxymethyl Cellulose-Water Based Casson Nanofluid from a Solid Sphere Generated by Mixed Convection under the Influence of Lorentz Force

Abstract

<jats:p>The heat transfer of a carboxymethyl cellulose aqueous solution (CMC-water) based Casson nanofluid, flowing under the impact of a variable-strength magnetic field in mixed convection around a solid sphere, has been examined in this work. Aluminum (Al), copper (Cu), and silver (Ag) nanoparticles were employed to support the heat transfer characteristics of the host fluid. A numerical approach called the Keller-box method (KBM) was used to solve the governing system for the present problem, and also to examine and analyze the numerical and graphic results obtained by the MATLAB program, verifying their accuracy through comparing them with the prior literature. The results demonstrate that a Al–CMC-water nanoliquid is superior in terms of heat transfer rate and skin friction. The velocity of CMC-water is higher with Ag compared to Al–CMC-water, and Ag–CMC-water possesses the lowest temperature. Growing mixed parameter values result in a rising skin friction, velocity and Nusselt number or decline in temperature.</jats:p>

Numerical investigation of heat transfer characteristics for blood/water-based hybrid nanofluids in free convection about a circular cylinder

“…Diverting from the vertical plate approach, recent studies considered the convection boundary layer flow over a horizontal circular cylinder, solid sphere, etc. For example, some researchers [19][20][21][22] studied the convection boundary layer flow in nanofluid past a solid sphere and horizontal circular cylinder. More studies on the boundary layer flow in a nanofluid over cylinder are given in the following references [23][24][25][26].…”

Entropy analysis of radiative [MgZn6Zr-Cu/EO] Casson hybrid nanoliquid with variant thermal conductivity along a stretching surface: Implementing Keller box method

“…They demonstrated that increasing the Casson parameter reduces local skin friction, velocity, or temperature and increases the local Nusselt number. The other researchers that have been investigating are Ullah et al, 11 Gbadeyan et al, 12 Rasool et al, 13 Alwawi et al, 14,15 to name a few. In recent years, the nanofluid has been extended to hybrid nanofluid to enhance the fluid characteristics.…”

Heat Transmission Reinforcers Induced by MHD Hybrid Nanoparticles for Water/Water-EG Flowing over a Cylinder

“…Dogonchi et al [44] numerically studied the impacts of a magnetic field and joule heating on a nanofluid over a stretching plate considering Brownian motion. Alwawi et al [45,46] modeled the magneto-free/mixed convection flow of Casson nanofluid over a solid sphere. The reader may also refer to Refs.…”
