Abstract

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.
具有空间依赖性能量源/汇的对流-磁性三混合纳米流计算方法:药物输送
氧化铁、银、氧化铝,这些纳米粒子单独或组合在一起有助于药物输送,特别是氧化铝纳米流体用于一种名为 "替米沙坦 "的抗血压药物。氧化铝和银粒子用于制造纳米复合材料,具有更强的抗菌性能。这就是目前研究三元纳米流体在双向片中的自然对流和能量传递效率的原因。目前正在对三元纳米流体(Fe3O4、Ag、Al2O3)进行分析。水(H2O)是传统的基础流体。采用两种不同的三元纳米流体组合,得出在热辐射、磁场、产热和吸热以及纳米粒子体积量等各种物理影响下的平均传热率、混合比(Fe3O4 + Ag)和(Fe3O4 + Ag + Al2O3)。在 MATLAB 编程的帮助下,可以使用 Keller box(有限差分)方法求解所开发的方程组数值结果。这种方法有助于从高阶偏微分方程(PDE)到常微分方程(ODE)的求解。研究结果表明,三元混合纳米流体的比热容直接受温度影响。努塞尔特数、速度曲线、表皮摩擦系数和温度曲线的数值解都借助图表来表示。与混合纳米流体(Fe3O4 + Ag/H2O)相比,三元混合纳米流体(Fe3O4 + Ag + Al2O3/H2O)在体积分数增加时传输更多能量。研究表明,金属氧化物比金属氧化物从系统中传递更多的热量。氧化铝纳米流体的传热率估计误差较大,其次是银纳米流体和氧化铁纳米流体。流线间距相等,但 M, S = 1 情况下的能量流量高于 M, S = 2。但在拉伸比参数的情况下,α = 0.5 时的能量流大于α = 1.0 时的能量流。在不同的 Biot 数下,观察到的能量流数量相同。
