Analytical and graphical studies are conducted on the impact of carbon nanotubes in aligned magnetohydrodynamics (MHD) mixed convection flow of nanofluid over an inclined plate. Various types of parameters are considered throughout the numerical study with a constant wall temperature. The similarity transformation was implemented to transform the partial differential governing equations into ordinary differential equations. Furthermore, the Fourth-Order Runge Kutta algorithm is built into Maple Software to solve the transformed equations. The analysis shows how various dimensionless parameters; the angle of magnetic field, the interaction of magnetic, the angle of an inclined plate, the volume fraction of nanoparticles, and mixed convection, affect velocity and temperature profiles, as well as how carbon nanotubes with various base fluids affect skin friction and the Nusselt number. As a result, for both types of carbon nanotube nanofluids, SWCNT/kerosene and MWCNT/kerosene, an increase in angle of magnetic field, interaction of magnetic, and mixed convection parameter risen the velocity profile while an increase in angle of inclined plate and volume fraction of nanoparticles enhanced the temperature profile. However, the Nusselt number and skin friction coefficients increase with increasing angle of magnetic field, interaction of magnetic, and mixed convection parameter and decrease with increasing inclined plate angle and volume fraction of nanoparticle. It was found that MWCNT transferred heat more efficiently than SWCNT

The current study scrutinizes the impact of heat and mass transfer on the slip flow of a nanofluid in a rotating system, which is designed by two infinite parallel plates. The effects of a magnetic field, thermal radiation, and chemical reaction are also added to the flow system. Copper oxide (CuO) is considered the nanomaterial with drinking water as the base fluid. The governing partial differential equations are transformed into a system of nonlinear ordinary differential equations with the help of similarity transformations. These equations are solved analytically by employing the least square method (LSM) and the Galerkin method (GM). The results computed by these methods are compared with the numerical method such as the Runge–Kutta method of order four (RK4M). The extensive applications of LSM and GM in comparison with RK4M are also presented. Although the attained outcomes are in good agreement, the results obtained with GM are more accurate than that obtained with LSM. Moreover, the contributions of various fluid parameters on the velocity, temperature, and concentration of the fluid are discussed through graphs. Results reveal that the presence of slip in the boundary declines the fluid velocity. The rotational velocity is enhanced with the increment of the rotation parameter. The magnitude of the skin friction coefficient is reduced by increasing the nanoparticle volume fraction while it grows by rising the magnetic parameter. The Nusselt number shows an enhancement with nanoparticle volume fraction, and it yields a slight reduction by increasing the effect of a magnetic field.

“…The suspended nanoparticles can be chosen widely according to the specified demands because of their diverse variety such as Al 2 O 3 , Cu, CuO, TiO 2 and Ag. In addition, the carbon nanotubes and multiwalled carbon nanotubes are considered as the nanoparticles and spread into the kerosene oil–based fluid to investigate their influence on the heat transfer enhancement (Hossain et al , 2022b; Hossain et al , 2022a).…”

“…Beyond the simple geometries, Giwa et al (2020) recently reviewed the research articles about MHD convection behaviors of nanofluids inside the non-square enclosures, and reported that such cases have attracted more attention of researchers than the square cavity in the past decade. Diverse numerical methods such as finite element method (Ahmed and Rashed, 2019; Job et al , 2017), finite element-based Galerkin weighted residual method (Islam et al , 2022; Hossain et al , 2022b; Hossain et al , 2022a; Keya et al , 2022), control volume finite element method (Sheikholeslami and Rokni, 2017), dual reciprocity boundary method (Oglakkaya and Bozkaya, 2016) and Lattice Boltzmann method (Mliki et al , 2017; Ashorynejad and Shahriari, 2018) were applied to discretize the complex geometry of the cavity. Usually, the nanofluid is the liquid-based rather than gas-based because the metallic nanoparticles suspended in the gas will rapidly settle to the bottom.…”

Purpose The purpose of this study is to investigate the enhancement and suppression of heat transfer for hybrid nanofluids (Cu–Al2O3/water) in a square enclosure containing a thermal-conductive cylinder when the Lorentz force is applied to the hybrid nanofluids. Design/methodology/approach Since the inner conductive cylinder in present research has a complex geometry, an in-house meshless method, namely, the local radial basis function (LRBF) method, is applied to solve the 2 dimensional (2D) incompressible Navier–Stokes equation in the fluid domain and Fourier heat conduction equation in solid domain. The solid–fluid interface remains the physical continuity of temperature and heat flux. Only the Lorentz force is considered for the presence of the magnetic field. The conjugate natural convection is assumed to be steady, thus only fully developed heat exchange from the nanofluids to solid or vice versa is comprehensively investigated. Findings It can be concluded that Lorentz force plays a more significant role than hybrid nanofluids in enhancing/suppressing heat transfer when the orientation of magnetic field is the same to the x direction. The thermal conductivity ratio can dramatically change the isotherms and streamlines as well as the mean value of the Nusselt number, resulting in totally different heat transfer phenomena. The included angle of magnetic field also has a significant effect on the heat transfer rate when it changes from horizontal to vertical. Research limitations/implications The constant thermo-physical properties of incompressible fluid and the 2D steady flow are considered in this study. Originality/value The conjugate MHD natural convection of hybrid nanofluids is numerically investigated by an in-house meshless LRBF method. The enhancement and suppression of heat transfer under the combined influence of the volume fraction of nanoparticles, Hartmann number and the thermal conductivity ratio are comprehensively investigated.
