“…The findings show that the velocity field decays with an increment in the Forchheimer parameter. Adopting the Darcy-Forchheimer model, Ali et al [20] have recently investigated the transient hybrid nanofluid flow generated by an extending cylinder with MHD and heat generation effects. The results indicate an amplification in the temperature distribution facilitated by the nanoparticle volume fraction.…”

Hybrid nanofluids are significant in biomedical, industrial, transportation, as well as several engineering applications due to their high thermal conductivity and mass transfer enhancement nature in contrast to regular fluids and nanofluids. Taking this into consideration, the present problem explores the flow of hybrid nanofluid (Ag − TiO 2/H 2 O) over a stretching cylinder subject to Newtonian heat and mass conditions. The novel aspect of the current work is to analyze the heat and mass transfer characteristics of MHD hybrid nanofluid flow on Darcy-Forchheimer porous medium in addition to activation energy, nonlinear thermal radiation, heat generation/absorption, viscous and Joulian dissipation. Further, Silver (Ag) and Titanium oxide (TiO 2) are the constituent nanoparticles of the water-based hybrid nanofluid owing to their stable chemical features and extensive industrial manufacturing. By introducing suitable similarity transformations, the governing partial differential equations (PDEs) of the developed model are reduced to ordinary differential equations (ODEs), and then the numerical solution is procured with shooting technique by using MATLAB solver bvp4c. The influence of the pertinent parameters is depicted graphically and described elaborately. The analysis indicates that velocity exhibits a declining trend against the permeability and Forchheimer parameters, while the temperature profiles show opposite behavior. The radiation and conjugate heat parameters (R, γ 1) upgrade the heat transfer rate, while the curvature and conjugate mass parameters (α c , γ 2) amplify the mass transfer rate. The maximum heat transfer rate of Ag − TiO 2/H 2 O hybrid nanofluid is 2.3344 attained for γ 1 = 0.6. The investigation demonstrates larger heat and mass transfer rates for Ag − TiO 2/H 2 O hybrid nanofluid than Ag − H 2 O nanofluid. The outcomes of the present investigation have practical applications in conjugate heat transfer over fins, development of vaccines, effluent treatment plants, solar cells, heat exchangers, and many more. An excellent agreement is achieved on comparing our numerical results with the published results in the literature.

In many mechanical systems, the friction is a major aspect in the energy loss. However, lubrication is the ultimate way to reduce friction. The engine‐oil is the prominent lubricant for internal combustion engines. Last few decades, nanofluids gained credit as an inventive low‐friction technology that significantly lowers emissions and keeps great energy savings. Therefore, this study analyzes the thermo‐diffusion Brinkman‐type radiative engine‐oil based unsteady magnetohydrodynamics heat consuming Molybdenum‐disulfide nanofluid flow with Hall, chemical reaction and viscous dissipation impacts from a rotating plate in porous environs. The finite difference numerical scheme was utilized to get the numerical solutions of the flow fields. The numerical results accomplished for velocity, temperature and concentration relating to assorted flow parameters with the help of MATLAB are interpreted graphically whilst the engineering quantities by tables. The ultimate results bring‐out that the temperature and both velocity components upsurges due to viscous dissipation and radiation effects but heat consumption affects oppositely. The nanoparticle's volume fraction significantly improves the temperature field. The Brinkman parameter and nanoparticle's volume fraction causes to slow‐down both velocity components whereas thermo‐diffusion and Hall parameters have exposed opposite impact. The magnetic field and rotational parameters tend to downgrade the primary velocity and heightens the secondary velocity. The concentration field repressed by the chemical reaction reagent. Heat transfer rate enhanced at the surface by increasing viscous dissipation and volume fraction but it is lessened with radiation and heat‐consumption. Interestingly, the heat transfer rate significantly raises to when dispersing Molybdenum‐disulfide nanoparticles to engine‐oil which enhanced its lubrication.
