“…On their interest study of MHD hybrid Cu–Al 2 O 3 /H 2 O nanofluid flow past a permeable stretching sheet by Wahid et al (2020), it was stated that the reduced Nusselt number increases as the Cu-nanoparticle volume fraction is escalated. There are several papers on HNFs available in the literature reviewing; for example, see Sarkar et al (2015), Sidik et al (2016), Sundar et al (2017) and Eshgarf et al (2021) and in the recently published papers related to the boundary layer in Aly and Pop (2019), Waini et al (2019, 2020), Aly and Ebaid (2021), Balaji et al (2021), Aly et al (2021), Sepehrnia et al (2022), Usafzai et al (2022), Usafzai and Aly (2022), Xuan et al (2022), Waqas et al (2022), Khashi’ie et al (2022), Roşca et al (2022), Roy and Pop (2022), Said et al (2022), Aly et al (2023) and also in the four interested books by Das et al (2007), Shenoy et al (2016), Nield and Bejan (2017) and finally Merkin et al (2022).…”

Purpose This paper aims to study the magnetohydrodynamic (MHD) wall jet of a hybrid nanofluid flow over a moving surface with a thermally convective surface, wall moving with suction/injection. Design/methodology/approach On using appropriate similarity transformations, the governing equations that describe the model are converted into a system of nonlinear ordinary differential equations. These equations are solved both analytically and numerically using standard two-point boundary-value problem solvers and Chebyshev pseudospectral differentiation matrix method, respectively. Findings These results show that the HNF is heating/cooling with growth of the positive/negative values of the parameter measuring the velocity of the moving surface. The temperature distributions increase, where the thermal boundary layer gets thicker, as the magnetic field strengthens and with an increase in the absolute value of the Biot number. Originality/value The current findings for the HNFs are new and original. They generalize successfully the problems investigated previously by different researchers for the cases of fluids and also nanofluids.

“…The effect of a magnetic dipole on the flow over a stretching sheet with combination of solid particles is discussed by Gul et al [9]. Recently, different authors [10][11][12][13][14][15][16][17][18][19][20] examined various hybrid nanofluid flows over distinct geometries. Chemically reaction is vital in mass transfer procedures involving high temperatures, such as nuclear power plants, gas production, central grain storage, oil, geo-thermal energy and thermal energy storage.…”

An exciting new class of heat transmission fluids, nanofluids, has been developed as an alternative to traditional fluids in manufacturing. Fuel cells, heat exchangers and pharmaceutical processes are just a few of the many uses for them. When compared to monofluids, the heat transmission properties of hybrid fluids are superior. These are findings used in an extensive diversity of fields, from solar energy to air conditioning. The objective of this paper is to examine how Lorentz force and chemical reaction parameters affect the characteristics of a couple stress hybrid nanofluid (Ethylene Glycol + Graphene + Copper) flow via an exponentially stretching surface. The heat transport phenomenon is studied using viscous dissipation, exponential heat source and thermal radiation parameters. Furthermore, irreversibility analysis is provided in this paper. Governing equations are transformed into a set of nonlinear ordinary differential equations using suitable similarity transformations. The bvp4c solver in MATLAB is used to solve the transformed system. Engineering parameters of interest, including skin friction coefficient, are described using bar diagrams. It has been noted that the magnetic field and volume fraction of graphene nanoparticles (ϕ1) reduce the skin friction coefficient. At , the skin friction coefficient decreases at a rate of 4.68187. It is observed that there is an increment in the fluid temperature with the rise in the exponential heat source parameter, and the velocity profile increases with the increase in the mixed convection parameter. It is detected that, while Eckert number () was set to , Nusselt number was reduced by 6.29239. It is noticed that, while the chemical reaction () is set to , the mass transfer rate rises at a Rate of 0.349644. It has been observed that as the Brinkmann number and magnetic field parameters increase, so does the rate of entropy production. It is also detected that as the porosity parameter increases, the fluid momentum decreases. Furthermore, increasing the couple stress parameter decreases the fluid velocity.
