Iron oxide, Silver, Aluminium oxide, these nanoparticles individually or combined help in drug delivery especially aluminium oxide nanofluid used in an anti-blood pressure drug called 'Telmisartan'. Alumina and silver particles are used in manufacturing nanocomposites which have more antimicrobial properties. This is the reason for the current study of ternary nanofluids natural convective flow and efficacy of energy transfer in a bi-directionally sheet. Currently, ternary nanofluids (Fe3O4, Ag, Al2O3) are being taken for analysis. Usual water (H2O) is the conventional base fluid. Two different combinations of ternary nanofluids are used to get the average heat transfer rate, mixture ratios (Fe3O4 + Ag) and (Fe3O4 + Ag + Al2O3) when subjected to a variety of physical influences, including thermal radiation, magnetic fields, heat production and absorption, and nanoparticle volume amount. It is possible to solve the developed set of equations numerical results using the Keller box (finite differences) method with the help of MATLAB programming. This method helps in solving higher order partial differential equation (PDEs) to ordinary differential equation (ODEs). The investigations findings demonstrated that the ternary hybrid nanofluids specific heat capacity is directly impacted by temperature. Numerical solutions for Nusselt number, velocity profile, skin friction coefficient, temperature profiles have represented with the help of graphs and tables. The ternary hybrid nanoflow (Fe3O4 + Ag + Al2O3/H2O) transmits more energy for increasing volume fractions, comparing to the hybrid nanofluid (Fe3O4 + Ag/H2O). The study reveals the fact that metal oxides transfer more heat from the system than that of metals. The estimated error of heat transfer rate is higher in alumina nanoflow followed by silver and iron oxide nanofluid flows. The streamlines are equally spaced, but the energy flow amount is higher for the case M, S = 1 than M, S = 2. But in the case of stretching ratio parameter, the amount energy flow in α = 0.5 > α = 1.0. An equal amount of energy flow is observed for varied Biot number.

“…Even though hybrid nanofluids are said to have better heat transfer capability in the majority of situations, further research is still necessary [19]. The recent fundamental and numerical studies of BLF concerning the use of hybrid nanofluids were conducted by Wahid et al, [20], Mousavi et al, [21,22], Khashi'ie et al, [23][24][25][26], Mahmood et al, [27] and Rafique et al, [28]. For the surface criteria, a stretching sheet typically enables a viable boundary layer solution as it naturally induces suction towards the surface, facilitating the flow.…”

This work features the numerical computation and statistical analysis (response surface and sensitivity) for the flow and thermal progress of an axisymmetric copper-alumina/water hybrid nanofluid subjected to a permeable shrinking disk. The simultaneous factors of magnetic field (MHD), heat generation and suction parameter in the heat transfer development and flow characteristic are observed. The flow and energy equations are mathematically developed based on the boundary layer assumptions. These equations are then simplified with the aids of the similarity variables. The numerical results are then generated by the bvp4c solver in the Matlab software. The dual solutions are possible and exist up to a separation value upon the inclusion of suction effect. The increment of heat generation parameter from 0% to 1% reduces the heat transfer rate for all values of the stretching/shrinking parameter. For the response surface analysis, the responses (skin friction coefficient and heat transfer rate) are analyzed for three factors (magnetic, suction, heat generation) and three magnitudes (low, medium, high). Based on this analysis, the magnetic and suction parameters provide a significant effect on the skin friction with p-values < 0.05. Meanwhile, for the heat transfer coefficient, all factors give significant impact with zero p-values. Meanwhile, the sensitivity analysis reveals that the suction parameter has higher sensitivity to the heat transfer as compared to the magnetic and heat generation parameter. Even though these parameters being less sensitive, their influence on heat transfer remains statistically significant.

“…Moreover, researchers have identified the existence of dual or multiple solutions arising from flow problems across a shrinking sheet. They have subsequently executed an identical analysis to validate the stability and physically realizable solution, such as Ishak [34], Lund et al [35], Yahaya et al [36], Waini et al [37], Khashi'ie et al [38], and Rasool et al [39].…”

The dynamics of unsteady flow of a ternary hybrid nanofluid on a stretching/shrinking sheet with wall mass suction is numerically analysed. In this study, a mixture of Al2O3, Cu, and TiO2 is employed as additives in water, which serves as the base fluid. The equations governed the problem are simplified into a collection of ODEs by adopting the similarity transformation. Maintaining the flow on a shrinking sheet is reliant on the essential aspect of suction. Furthermore, augmenting the strength of suction amplifies the thermal conductivity process of the flow. Additionally, this study unveils dual solutions existing within a defined range of parameters. It has been determined that one solution exhibits long-term stability, whereas the other solution is deemed unstable through the stability analysis conducted.
