“…The heat transfer of multiwall carbon nanotubes (MWCNTs) or akerosene nanoliquid in the channel having heat sink has been inspected by Abedin et al 8 Sarlak et al 9 studied the numerical optimization of a double‐covered channel with a heat sink by considering a CNT nanofluid with non‐Newtonian viscosity. Ganji et al 10‐15 investigated on different fluid flows in various systems by considering the nanoparticle shape factor and several base fluids. Ayele and Wubshet 16 reveal the dissimilarity in velocity and temperature fields of MWCNT and singlewall carbon nanotube (SWCNT) nanoliquids.…”

This study has been conducted to focus on magnetohydrodynamic flow of a nanoliquid through a microchannel in the presence of a magnetic field. In this article, carbon nanotubes suspended in an aqueous medium were our considered fluid, and we focused on both singlewall and multiwall carbon nanotubes. The numerical calculations have been made via the fourth‐ and fifth‐order Runge–Kutta–Fehlberg method. The flow of the nanoliquid in a microchannel with porosity has been scrutinized with the existence of mutual effects, like, the nanoparticle volume fraction, suction or injection, thermal‐dependent heat source, convective boundary conditions, Darcy friction factor, and thermal motion of the nanoparticles. The influence of every major parameter on the profile of momentum, temperature, and entropy generation has been displayed graphically, and we discuss their physical aspects. The numerical outcomes demonstrated that the momentum profile augmented with the buoyancy force, angle of inclination, and Darcy number. Thermal energy was enriched with the heat source parameter, Darcy number, and Hartmann number. The irreversibility rate declined with the volume fraction of nanoparticle and radiation parameter, while it increases with the buoyancy force, Eckert parameter, and Darcy friction factor.

The remarkable aspects of carbon nanotubes like featherweight, durability, exceptional electrical and thermal conduction capabilities, and physicochemical stability make them desirous materials for electrochemical devices. Having such astonishing characteristics of nanotubes in mind our aspiration is to examine the squeezing three dimensional Darcy–Forchheimer hydromagnetic nanofluid thin-film flow amid two rotating disks with suspended multiwalled carbon nanotubes (MWCNTs) submerged into the base fluid water. The analysis is done by invoking partial slip effect at the boundary in attendance of autocatalytic reactions. The mathematical model consists of axial and azimuthal momentum and magnetic fields respectively. The tangential and axial velocity profiles and components of the magnetic field are examined numerically by employing the bvp4c method for varying magnetic, rotational, and squeezing Reynolds number. The torque effect near the upper and lower disks are studied critically using their graphical depiction. The values of the torque at the upper and lower disks are obtained for rotational and squeezed Reynolds numbers and are found in an excellent concurrence when compared with the existing literature. Numerically it is computed that the torque at the lower disk is higher in comparison to the upper disk for mounting estimates of the squeezed Reynolds number and the dimensionless parameter for magnetic force in an axial direction. From the graphical illustrations, it is learned that thermal profile declines for increasing values of the squeezed Reynolds number.

Simulation of magnetohydrodynamics (MHD) free convection and radiation in a cavity packed with CuO‐water nanofluid has been numerically performed. To gain the outputs, control volume‐based finite element method (CVFEM) has been used. The physical domain is considered porous space and new model has been involved for modeling. This review covers a broad range of Rayleigh number, Hartmann radiation parameter, nanoparticles' shape on nanoliquid behavior, and interface heat transport variable were validated. The obtained average Nusselt number is compared with that of Rudraiah et al. for higher estimations of Gr and Ha at Prandtl number 0.733 and found good analysis with them. Furthermore, the temperature distribution of the present work on the axial midline between the obtained outcomes and computational outcomes of Sharif et al. and Khanafer et al. subject to Gr = 104, ϕ = 0.1, and Pr = 6.2(Cu − Water). It is also noticed that the conduction phenomenon is more significant against rising Nhs, while heat transfer rate declines. The convective mode strongly depends on shape factor of various nanoparticles, that is, platelet, spherical, brick, and cylinder.
