“…A comparative investigation of the outcome of chemical reaction considering multiple hybrid nanofluids flowing across a surface having curvature, using the MBM, was presented by Mishra and Upreti [39]. Recently Barman et al [40] have conducted an investigation of the MHD flow of Cu − Al 2 O 3 /H 2 O hybrid nanofluid over a rotating sphere. The problem was modeled using the MBM, and the findings indicate a boost in the mass transport rate with the thermophoresis parameter.…”

The current research investigates the magnetohydrodynamic (MHD) slip flow of second-grade nanofluids past a permeable stretching sheet in a porous medium. The flow analysis is accomplished considering thermophoresis, Brownian diffusion, chemical reaction, and elastic deformation. The implementation of the Modified Buongiorno model (MBM) on second-grade nanofluid is the novel aspect of the study. The formulated coupled nonlinear equations are non-dimensionalized, applying suitable similarity transformation. Numerical resolution of the resulting equations is achieved via MATLAB solver bvp4c. In our problem, two different groups of nanofluids, $Cu-EO$ and $TiO_2-EO$, have been considered. The development of profiles of nanofluid velocity, temperature, concentration, entropy generation and Bejan number, with the flow parameters, is elaborated graphically. Tabulated values of skin friction, Nusselt number, and Sherwood number are illustrated. The principal outcomes of this study demonstrate a higher rate of heat transfer of $Cu-EO$ nanofluid than $TiO_2-EO$ nanofluid. The Nusselt number significantly decelerates, and the Sherwood number accelerates due to the combined influence of the Brownian diffusion and thermophoresis parameters. The second-grade parameter and nanoparticle volume fraction boost the skin friction magnitude. Furthermore, the entropy generation increases due to the Brinkman number and concentration diffusion parameter. The present research can be utilized to enhance the effectiveness of cooling systems in automobile engines, nuclear reactors, and heat exchangers. For the validation of our result, a comparative study is made with the previous authors and concludes in good agreement.

The primary objective of this study is to quantify the rate of entropy generation within the Magnetohydrodynamic (MHD) slip flow system over the inclined needle. Entropy generation is a measure of the irreversibility and inefficiency in the flow process. The slip flow condition at the fluid interface can significantly impact the flow characteristics and heat transfer rates. In the hybrid nanofluid flow, which consists of non-magnetic and magnetic (Al2O3 and Fe3O4) are nanoparticles, are considered as the base fluid. Furthermore, the effects of inclined magnetic fields are taken into interpretation. The PDE’s governing equations are converted into ODE’s using similarity transformations and solved by a numerical technique based on BVP4C. The results illustrate that crucial parameter such as the magnetic parameter, mixed convection parameter, nanoparticles of solid volume fractions, and Prandtl numbers are pointedly impacted by momentum and thermal profiles. The entropy and Bejan number also consider being various relationship combined parameters. These analyses protest that raising the magnetic parameter estates an increase in the hybrid nanofluid thermal profile under slip circumstances. Examined magnetic field impact on flow and entropy generation in MHD flows, revealing significant changes in entropy generation due to interaction between magnetic field and nanoparticles. This analysis understands the impact of MHD and slip effects on entropy generation, particularly in the context of the newly emerging 50:50 fluid mixture. Hybrid nanofluids have been shown to have improved thermal conductivity compared to traditional fluids, which can enhance the cooling or heating capabilities of the inclined needle.

“…Friction increased due to enhancing the nanoparticles while decrease due to higher Reynold's number. Barman et al [8] investigated entropy generation in MHD fluid with hybrid nanoparticles, flowing via rotating sphere having a radiational effect having nonerratic slot-to-slot transfer. Quasi linearization approach is used with FDM (finite difference method) to get numerical solutions.…”

In this study, we investigate the electromagnetohydrodynamic (EMHD) Eyring–Powell hybrid Nanofluid flowing through a stretching surface, with the effects of copper , aluminum oxide nanoparticles and gyrotactic motile microorganism with polyvinyl alcohol‐water as a base fluid. Heat transfer, joule heating, solar radiation, mass transmission, and entropy generation effects are analyzed on the fluid flow. A numerical model with an analytical methodology for the description of fluid flow and thermal properties of a parabolic trough solar collector (PTSC) installed on a solar plate is underway as the use of solar plates in many devices going to expand. The governing partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) by using similarity transformations. The higher‐order ODEs are then solved using the analytical scheme known as the homotopy analysis method (HAM) in MATHEMATICA. The effects of different parameters such as magnetic field, electric field, Prandtl number, Eckert number, bioconvection diffusion, Lewis number, chemical reaction parameter, bioconvection, and Grashof number are analyzed with flow characteristics graphically. The velocity of the fluid shows a decrement due to the radiation parameter, Grashof number, and Solutal Grashof number. Thermodynamic properties of the fluid are enhanced with the Prandtl number, Eckert number, and electric and magnetic field. The entropy of the fluid increases with the Prandtl number, Eckert number, and diffusion parameter. Bejan number rises due to diffusion and bioconvection diffusion parameters. The study is about the mathematical analysis of Eyring Powell fluid flowing through a PTSC with the addition of a motile microorganism. PTSC are a main source of energy production for many sectors. Nanoparticles of copper and aluminum oxide are mixed to raise the thermal properties of the fluid used for electricity production engines, solar energy systems, cooling devices. Solar radiation effect, Joule heating, and viscous dissipation are analyzed for the energy production devices.
