Magnetic field involvement can influence heat absorption in electrically conducting fluid flow, which is useful in the control of features of final products in industries such as radiation therapy, aeronautics, and MHD generators. Consequently, this study investigates the effect of an aligned magnetic field on nanofluid flow over a stretching sheet with the boundary condition of Newtonian heating. Steady nanofluid flow with copper as chosen nanoparticles and water as conventional base fluid is considered. The problem is governed by a system of nonlinear boundary layer equations with appropriate boundary conditions which are then transformed into non-dimensionless equations using an appropriate similarity transformation. A numerical approach known as Keller-Box method is used to solve the transformed governing equations. The numerical solutions obtained are presented graphically in the form of velocity and temperature profiles for different values of aligned angle of magnetic field, Newtonian heating parameter, Prandtl number and nanoparticles volume fraction. A significant increase in aligned angle results in a decrease in fluid velocity, but an increase in temperature profile of nanofluid flow. The increment in the Newtonian heating parameter as well as the nanoparticle volume fraction also causes the temperature to increase.

Numerous physical characteristics occurring from the structure and micro-motions of fluid nanoparticles can be examined using the governing models of nanofluids. Also, It can describe the demeanor of a vast field of actual fluids. This achieved a significant turn in the enhancement of heat transfer that improves manufacturing and engineering modernization. Depending on that, the assumptions that form our aims are numerically examining energy transport and heat transfer via Casson ternary hybrid nanofluids that contain the states of combined convection flow over a vertical stretching sheet. Also, Newtonian heating boundary conditions and magnetohydrodynamics (MHD) effects are investigated. Mathematical models (governing equations) that emulate and construct the conduct of these boosted ternary hybrid nanofluids are formed by developing the Tiwari and Das models. These governing equations are converted to partial differential equations (PDEs) employing appropriate substitutions. An accurate and efficient method called the Keller box numerical method is executed to get outcomes to the physical model. These numerical calculations are found and presented by employing MATLAB codes, to acquire tables of numerical outcomes, and graphic exhibits, which provide the impacts of important parameters on the physical quantities supporting heat transfer. Furthermore, the new results, in the Newtonian fluid case, were compared with prior literature, which were in excellent agreement. The studied problem parameters are examined at a Casson parameter domain of 1 to 5, a mixed convection parameter domain of -1 to 3, a conjugate parameter of 0.2 to 1, a magnetic parameter domain of 0.1 to 5, and a nanoparticle volume fraction parameter of 0.001 to 0.008. The numerical consequences deduced that the local skin friction rises when the conjugate and mixed convection parameters are increased. But the opposite case happens when the effects are obtained for the nanoparticle volume fraction, magnetic, and Casson parameters. Also, the Nusselt number rises with growing nanoparticle volume fraction and Casson parameters.

“…It was found that heat transfer enhancement increases by increasing of hybrid nanofluid volume concentration and volume flow rate. Recently, the study of hybrid nanofluids on flow over various situations was considered by researchers, such as over a vertical, solid sphere, stretching/shrinking sheet, bioconvection and others [8][9][10][11][12][13][14][15][16][17].…”

The current study examined the effect of nanoparticles shapes on magnetohydrodynamics (MHD), Casson hybrid nanofluids flow, and heat transfer over a moving vertical plate with convective boundary condition. In this study, a base fluid (water) was infused with silver (Ag) and titanium oxide (TiO2). Similarity transformation techniques are used to convert the partial differential equations of Casson hybrid nanofluids to an ordinary differential equation, which are then solved numerically by applying the implicit finite difference, Keller box method. The velocity and temperature profiles, skin friction, and Nusselt number of Casson hybrid nanofluids were graphically illustrated and numerically tabulated. The results indicate that platelets have the highest velocity and temperature profiles, followed by cylindrical, bricks, and spherical nanoparticles. It was discovered that as the parameters aligned angle of the magnetic field, magnetic field interaction, mixed convection, Casson hybrid nanofluids, and Biot number increase, the velocity increases while the temperature decreases. As the volume fractions of Ag and TiO2 nanoparticles increase, the velocity decreases while the temperature increases. Except for the Casson hybrid nanofluids parameter, the skin friction and Nusselt number increase as the aligned magnetic angle, magnetic field interaction, mixed convection, volume fraction of Ag and TiO2 nanoparticles, and Biot number is increased. For all parameters, the plate with the condition moving with the flow has the highest velocity and Nusselt number, followed by the static and moving against the flow plates. When it comes to temperature and skin friction, the plate that is moving against the flow has the highest temperature, followed by the plate that is static and moving along the plate. The findings of this work will contribute to the corpus of knowledge in mathematics by providing fresh information for mathematicians interested in future research on Casson hybrid nanofluids.
