Computational Valuation of Darcy Ternary-Hybrid Nanofluid Flow across an Extending Cylinder with Induction Effects

The flow of an electroconductive incompressible ternary hybrid nanofluid with heat conduction in a boundary layer including metallic nanoparticles (NPs) over an extended cylindrical with magnetic induction effects is reported in this research. The ternary hybrid nanofluid has been synthesized with the dispersion of titanium dioxide, cobalt ferrite, and magnesium oxide NPs in the base fluid water. For a range of economical and biological applications, a computational model is designed to augment the mass and energy conveyance rate and promote the performance and efficiency of thermal energy propagation. The model has been written as a system of partial differential equations. Which are simplified to the system of ordinary differential equations through similarity replacements. The computing approach parametric continuation method is used to further process the resultant first order differential equations. The results are validated with the bvp4c package for accuracy and validity. The outcomes are displayed and analyzed through Figures and Tables. It has been observed that the inverse Prandtl magnetic number and a larger magnetic constant reduce the fluid flow and elevate the energy profile. The variation of ternary hybrid NPs significantly boosts the thermophysical features of the base fluid.


Introduction
In general, vortex shedding around a circular cylinder cause resonance and structural vibrations, as well as increases in mean drag and lift fluctuations. As a result, vortex shedding flow management is important for engineering applications, as it can successfully result in vibration and noise reduction, drag reduction, and flow separation suppression [1]. Flow control over a circular cylinder has a long history of research. Many engineering methods use flow inside a cylinder, but flow over a canister in a limited domain, such as a stream in a lateral trench or pipe flow, has received significantly less attention. Many situations, such as blood flow across veins from operating sources or flow across cylindrical goods near walls, need wall effects to be taken into account while scaling a problem. Furthermore, while natural forms of unorganized and random exterior roughness have been examined, other types of ordered roughness have not. Vibrations during the printing process can cause curliness on the surface of a 3D-printed solid with regular periodic grooves [2]. Salahuddin et al. [3] examined the differently formed nanostructures that affected the mechanical performance and flow efficiency of flow due to rigid and sinusoidal barriers when heat is generated. Wu et al. [4] employed a wind tunnel with multiple active mechanisms to investigate the aerodynamic demands of a 5:1 rectangular sinusoidal radius cylinder. Varying the frequency and amplitude produces a consistent vorticity loop. Bilal et al. [5] studied a non-uniform Maxwell ferrofluid flow through a stretched cylinder with a non-fluctuating suction/injection. When the thermophoresis ratio is increased, the angular momentum of mass propagation increases significantly, while the radial and angular velocity decrease as the viscosity element improves. A statistical assessment of a 3D flow via a rectangular enclosure was demonstrated by Seo et al. [6]. The sinusoidal cylinder was compared against a circular cylinder to see if it could improve total convective efficiency. The cylinder shape had a significant impact on heat transfer, with performance improving by up to 27%. Bilal et al. [7] investigated the CNTs and iron oxide Fe 3 O 4 hybrid nanofluid using an inclined extensible cylinder. According to the research, hybrid NF is the most efficient heat enhancer and may be utilized for both heat transmission and cooling. Refs. [8][9][10] provide some other application uses and flow models.
Ternary hybrid nanofluid is an innovative type of fluid that outperforms at energy exchanges when compared to ordinary fluids, nanofluid, hybrid nanofluid, gasoline, and acetone. Hybrid nanofluids have a wide range of thermal implications, including freezing in high-temperature conditions [11]. Solar energy, heat pumps, heat exchangers, air purifiers, the auto sector, electrical chiller, turbines, nuclear networks, broadcasters, ships, and biotechnology are all examples of hybrid NFs in use. In this work, we are using ternary NPs consisting of titanium dioxide (TiO 2 ) cobalt ferrite (CoFe 2 O 4 ) and magnesium oxide (MgO). TiO 2 is a white inorganic compound that has been used in a variety of products for more than a decade. So it is dependable due to non-toxic, phosphorescence, and nonreactive properties, which boost the brilliance and luminosity of a wide range of products while posing no risk of injury. It is the world's lightest and whitest material, with reflective capabilities, UV absorption and emission qualities, and the ability to protect against skin cancer [12]. Cobalt (Co) and iron (Fe) are metals. Fe lowers interstitial resistance, allowing for charge/ion mobility on the surface and a considerable increase in specific capacitance [13,14]. MgO, often known as magnesia, is a highly absorbent white solid substance that exists organically as reaction products and is a magnesium resource. It is made up of a combination of Mg 2+ ions and O 2− ions bound by electrostatic interactions and has the general structure MgO [15]. The implications of electromagnetic fluxes on the heat transport of water-based iron oxide and CNTs hybrid NFs across dual rotational plates were studied by Bilal et al. [16]. The velocity profile is boosted by the electric variable, while the thermal factor is minimized. Ramesh et al. [17] used Fe 3 O 4 and CoFe 2 O 4 in water + EG to study the activation energy features on the movement of hybrid NF across a channel. Wang et al. [18] used a Fe 3 O 4 -MWCNT hybrid NF flow to simulate the impacts of conductive surface and nanocomposites on the thermal conductivity of a conventional solid heat sink. Arif et al. [19] observed ternary hybrid NF with distinct shapes, Al 2 O 3 , Graphene, and CNT. According to the findings, the ternary hybrid nanofluid improves heat transfer rates by up to 33.67% indicating good thermal performance in thermal efficiency. Sahoo et al. [20] addressed the heat transmission of a condenser with a new coolant made up of water-based nanoparticles, such as CNT, Al 2 O 3 , and graphene ternary hybrid NF. Variation in the quantity of NPs from 1 to 3% at 10 L/min resulted in increases of 22.34 and 6.63% in energy exchange, respectively. Fattahi and Karimi [21] conducted thermo-hydrodynamic tests on solar panels with water repellent coatings while employing a ternary hybrid nanofluid. Refs. [22][23][24][25] contain some relevant literature and applications of hybrid NPs in water for biomedical and engineering objectives.
Magnetization is one of the most important aspects in manufacturing and engineering, having a wide range of applications. The interaction of fluid nanoparticles with magnetic fields has an impact on the quality of heat transfer, clutches, and compressors, among other industrial commodities. Magnetic fields have the ability to control and make available the cooling rate of a variety of industrial devices. Interplanetary and astronomy magnetosphere uses, as well as aeronautics and chemical science, all rely on magnetic fields. The flow properties are influenced by the strength and dispersion of the administered metamaterials. Many academics submitted fluid mechanics research publications that described flow characteristics under the influence of a magnetic field. The influence of thermal expansion and a produced magnetic field on the oscillatory conveyance of a fourth order fluid via a vertical tunnel was investigated by Hayat et al. [26]. Raju et al. [27] investigated the effects of heat exchange and the pre-exponential component on MHD free convective flow across a semi plate. Refs. [28][29][30] contain some recent literature on MHD hybrid nanofluid.
To the best of the authors' knowledge, heat and mass transfer pass over a moving cylinder containing a ternary NPs, as well as magnetic induction, has not been studied to date. As a result, the current research focuses on this topic. In this scenario, the horizontally expanding cylinder is analyzed with a static applied magnetic field. With adequate far stream and wall conditions, the dynamic model is transformed into a system of ODEs. To obtain the solutions, the computational parametric approach process (PCM) is used. The second goal is to increase the efficiency and profitability of thermal energy propagation in a range of economic and biomedical fields.

Governing Equations
We considered an incompressible axisymmetric trihybrid nanofluid flow over a moving boundary layer cylinder. The x-axis is taken along the horizontal cylinder axis, whereas the r-axis is supposed towards the radial direction. The effect of induced magnetic is momentous due to the massive Reynolds number, which is consequently distorted by the magnetic effect. The magnetic field is normally applied to mutual constraints, H(H 1 , H 2 ). The H 2 (parallel component) is the induced magnetic field of the vertical element, which dispels at the surface of the cylinder. H 1 assumed value is H e = H 0 x at the free stream. The wall and far stream temperature are nominated as T w and T ∞ . Furthermore, the cylinder is assumed to be extended, with stretching velocity U w = U 0 (x/l), towards the axial direction, where U 0 is constant and l is the length of the cylinder, as shown in Figure 1. The fundamental calculations that regulate the fluid flow are defined as [31]: Here, Equation (1) denotes the law of mass conservation, which states that mass leaves and enters a system at the same rate. Magnetic flux is expressed mathematically as Equation (2), which provides information about the strength of magnetic flux in a given area of a surface. The component form of the momentum equation that characterizes the behavior of fluid flow is represented in Equation (3). Magnetic induction is represented by Equation (4) as a component form. Equations (5) and (6) are mathematical representations of the heat equation and concentration, respectively, which show the distribution of temperature (thermal energy) and mass around and near the stretching cylinder's surface, Here, Equation (1) denotes the law of mass conservation, which states that mass leaves and enters a system at the same rate.

Step 4: Apply the superposition principle For each element, we resolve the two Cauchy problems listed below.
By putting Equation (37) in Equation (35), we find Step 5: Solving the Cauchy problems This study makes use of a numerical implicit system, as seen below.
Finally, we see the iterative form as:

Results and Discussion
The graphical results of the system of DEs are assessed by commissioning the computational methodology "parametric continuation approach". The following are some of the conclusions that have been perceived:  Figure 2a,b exposed that the fluid velocity profile reduces with the effect of magnetic term β and Darcy Forchhemier term Fr. Physically, the surface permeability reduces with the rising effect of Darcy Forchhemier number, which results in the reduction in the momentum boundary layer. Therefore, such a scenario has been noticed. Figure 2c,d revealed that the curvature constant γ enhances the velocity profile, while the influence of inverse magnetic Prandtl number λ and nanoparticles volume friction ψ declines the momentum boundary layer, respectively. The curvature variable is lowered as the cylinder radius grows (inverse relation). In contrast, a shorter cylinder radius results in a stronger curvature impact, which promotes momentum propagation and velocity augmentation in the boundary layer as shown in Figure 2c. The rising quantity of nanoparticles enhances the density and visocsity of base fluid, which causes the reduction in the velocity profile (Figure 2e).

Magnetic Induction g (η)
Figure 3a-d emphasize the presentation of induced magnetic field g (η) versus the variation of the magnetic term β, curvature constant γ, inverse magnetic Prandtl number λ, and nanoparticles volume friction ψ, respectively. Figure 3a indicated that the magnetic induction profile reduces with the upshot of the magnetic term. The phenomenon is observed due to the opposing effect generated by the Lorentz force. Figure 3b,c display that the magnetic gradient function accelerated with the improving values of curvature constant γ and inverse magnetic Prandtl number. A larger curvature impact boosts the magnetic induction, signifying that a lower surface size of the extending cylinder facilitates magnetic dissemination as highlighted in Figure 3b. Changing the quantity λ creates reinforcement for the stream magnetic gradient curve. In the far flow field, the flow allocation evolves to a unity terminal in the reported cases. The magnetic Prandtl number is the relation of the frequency of magnetic dispersion to the rate of viscous diffusion. The reciprocal ratio, or the rate of viscous dissemination divided by the rate of magnetic diffusion, is denoted by λ. Figure 3d elaborated that the inclusion of ternary nanoparticles diminishes the induced magnetic field and fluid temperature. This is the actual property of ternary NPs, which makes them more efficient for industrial and biomedical uses. The rising quantity of NPs enhances the fluid kinetic viscosity, which results in a reduction in energy and velocity profile as well as magnetic induction g (η).

Temperature Profile θ(η)
Figure 4a-d exemplify the presentation of energy θ(η) profile against the variation of the magnetic term β, curvature constant γ, inverse magnetic Prandtl number λ, heat source Q 1 , and nanoparticles volume friction ψ, respectively. Figure 4a,b explain that the energy θ(η) profile boosts with the positive variation of magnetic term β and curvature constant. Physically, the friction produces due to Lorentz, which generates heat energy as well; as a result, the energy profile is enhanced. The variation in inverse magnetic Prandtl number λ and heat source Q 1 boosts the temperature of the fluid as seen in Figure 4c,d. Magnetic diffusion is consequently more helpful to the thermal diffusion process than viscous (momentum) diffusion, therefore such phenomena have been noticed in Figure 4c.
On the other hand, the effect of a heat source is generated, which causes the rise in energy profile shown in Figure 4d. As we have discussed in Figures 2 and 3, the inclusion of ternary nanoparticles improves the energy-absorbing capability of the base fluid, which eventually lowers the temperature θ(η) of the fluid as perceived in Figure 4e. energy as well; as a result, the energy profile is enhanced.

It has been observed that the tri-hybrid and hybrid nanofluid has a great tendency for the fluid energy and velocity transference rate as compared to the simple NF.
