A dynamic assessment of various non-Newtonian models for ternary hybrid nanomaterial involving partially ionized mechanism.

The dynamic of fluids and coolants in automobiles are achieved by enhancement in heat energy using ternary hybrid nanostructures. Ternary hybrid nanomaterial is obtained by suspension of three types of nanofluid (aluminum oxide, silicon dioxide and titanium dioxide) in base fluid (EG). Prime investigation is to address comparison study in thermal energy involving various flow models termed as Maxwell fluid and Williamson fluid. This exploration is carried out by partially ionized fluidic particles in the presence of ternary hybrid nanomaterial over cone. Heat transfer is carried out by heat source and thermal radiation. Equations regarding Ordinary differential are achieved from PDEs using variable transformations. The numerical consequences are obtained implementing finite element method. Flow into fluid particles is enhanced versus higher values of Hall and ion slip parameters. Thermal performance as well as flow performance for the case Williamson fluid is better than for case of Maxwell fluid. Production via energy is boosted versus heat source parameter.

Outcomes and discussion

The formulation of 3D model is developed in presence of Williamson fluid and Maxwell fluid. Dynamics behavior of tri-hybrid nanoparticles is implemented under ion slip and Hall currents. Heat source and thermal radiation are added into heat energy equation. The correlations in view of tri-hybrid nanomaterial along with thermal properties are added. Finite element approach is utilized to obtain numerical consequences. The combine study of Williamson and Maxwell liquids is analyzed. Explanations of graphical results are addressed below.

Dynamics analysis regarding velocity fields

Figures 3, 4, 5, 6, 7 and 8 are plotted to visualize comparative investigation among Maxwell fluid and Williamson fluid considering impact of Hall parameter, ion slip number, magnetic number and bouncy parameter on velocity field. It is noticed that solid curves are captured for behavior of Williamson liquid while dot curves are prepared for visualization of Maxwell fluid. Figures 3 and 4 is plotted to determine impact of magnetic parameter on velocity field in term of y- and x-directions. From this figure, it is estimated that motion regarding fluid particles is induced using wall velocity. However, impact of Lorentz force creates resistance among fluid particles using implication of magnetic parameter. The flow regarding fluidic particles becomes slow down when magnetic field is implemented. Lorentz force is produced using appearance of magnetic field. Flow is slow down because of negative Lorentz force is implemented. Additionally, magnetic parameter is formulated using concept of Lorentz force in momentum equations. Magnetic parameter is inserted along z-direction regarding fluidic motion. Due to opposite direction of flow and magnetic field, flow becomes slow down. Thickness regarding momentum layers is decreased when magnetic parameter is increased. Moreover, flow for case of appetence of magnetic field is higher than flow for the case of disappearance of magnetic field. Figures 5, 6, 7 and 8 are sketched to determine observation of ion slip and Hall parameters on motion regarding fluid particles in term of y- and x-directions. The acceleration is enhanced when ion slip and Hall parameters are increased. This is because ion slip and Hall parameters are appeared in generalized Ohm’s. Therefore, velocity of fluidic particles is increased. Moreover, it visualized that thickened based on momentum layers are higher for the cade Williamson fluid than as compared thickness for the case of Maxwell liquid. It is noticed that Lorentz force and magnetic parameter are declined when ion slip and Hall parameters are enhanced. The reduction of Lorentz force makes enhancement into fluidic motion. Further, and are appeared in denominator in momentum equations. Hence, inversely proportion relation is appeared versus Lorentz force. Therefore, flow in both directions is increased when and are increased. Thickness of momentum layers are decreased versus enhancement in and The flow for case of disappearance of and is higher than flow for the case of appurtenance of ion slip and Hall parameters.

Dynamics analysis regarding heat energy

Figures 9 and 10 are plotted to observe the behavior of thermal radiation number and heat source number on heat energy. It is estimated that comparative simulations among Williamson liquid and Maxwell fluid on heat energy is measured inserting ternary hybrid nanoparticles. Figure 11 captures comparison study into fluid, nanoparticles, nanofluid and hybrid nanofluid. The role radiation parameter on temperature curves are carried out by Fig. 9. From this figure, it is investigated that the production related to heat energy is reduced when radiation parameter is enhanced. It is because heat energy is transferred in term of away from the wall due to thermal radiation ways. Therefore, amount regarding thermal energy is reduced. Moreover, production related to thermal energy for the case of Williamson fluid is higher that production based on heat energy for the case of Maxwell fluid. Physically, heat energy moves away from the surface of rotating cone due to thermal radiation. Therefore, heat energy is reduced when thermal radiation number is increased. It is noticed that inverse proportional relation is observed versus impact of thermal radiation. An increment in thermal radiation number brings declination into heat energy. Thermal layers thickness of boundary layers is decreased when thermal radiation number is increased. Figure 10 predicts investigation of heat source parameter on heat energy. Heat energy is boosted when heat source parameter is increased. This is because heat source is implemented at wall via surface of sheet. Heat energy can be easily managed using heat source parameter. The impacts of two kinds impacts regarding are discussed which are based on heat source and heat generation phenomena’s. It is noticed that positive numerical values of are implemented for heat generation and magnetite numerical values of are implemented for heat absorption. Thickness related to thermal layers can be managed by variation in heat source parameter. Moreover, production related to thermal energy for the case of Williamson fluid is higher that production based on heat energy for the case of Maxwell fluid. Figure 11 illustrates visualizations of thermal enhancement inserting fluid, hybrid nanofluid, nanofluid and tri-hybrid nanofluid. It is noticed that solid curves are made by tri-hybrid nanofluid and dot curves are drawn for apprence of hybrid nanoparticles. Further, dash and dot dash curves are captured for fluid and nanofluid. From this figure, it is investigated that tri-hybrid nanoparticles are significant to obtain maximum amount regarding heat energy rather than hybrid nanoparticles, fluid and nanofluid.

Dynamics analysis regarding Nusselt number, divergent velocities and heat transfer rate

Table 4 demonstrates numerical effects of various (defined parameters) on velocity gradients and Nusselt number. From Table 4, it is studied that Nusselt number is reduced versus heat source, magnetic parameter but heat transfer rate is boosted when ion slip and Hall parameters are increased. It is noticed that divergent velocities are known as skin friction coefficients. The surface forces per unit area are termed as skin friction coefficients. Skin friction coefficients are declined versus impacts of ion slip and Hall parameters. Flow rates in term of vertical and horizontal directions become slow down versus increment values of Hall parameter and ion slip number. Heat source number produces declination into flow rates in term of vertical and horizontal directions. Comparative simulations among Williamson fluid and Maxwell fluid against change in magnetic number and Prandtl number are recorded in Table 5. It is estimated that heat transfer rate is enhanced versus variation in Prandtl number but heat transfer rate is declined against change in magnetic parameter. Additionally, production for heat transfer rate for case of Williamson liquid is higher than heat transfer rate for case of Maxwell fluid.
