摘要

纳米流体在热传递现象中表现良好,并产生了良好的结果,这吸引了科学家们悬浮其他纳米颗粒的组合,称为“混合纳米流体”。混合纳米流体比纳米流体优越,因为它们的热性能和新出现的好处有助于提高热传递率。这些纳米颗粒的应用,包括复杂的润滑剂,在生物工程和电力领域正在增加。本研究的主要前景是探讨水基双性质纳米流体通过带传热的不规则拉伸片的流动数值模拟。从这个角度来看,银与基液水一起被用作纳米流体的纳米颗粒,而为了制造混合纳米流体,氧化铜和银颗粒与水基流体一起使用。改进的傅里叶和菲克热流模型利用了上述现象,观察了热和质量的传递。利用相似变量将偏微分方程转化为相关的非线性常微分方程,然后利用MATLAB数学软件中的内置函数bvp4c进行计算求解。在并行近似的基础上,进行了改造,以确定各种量对流量变量的影响。预测结果通过图形描述以速度、温度和浓度剖面来描述。综上所述,混合纳米流体具有比普通纳米流体更强的传热特性。速度剖面随Darcy-Forchheimer参数的增大而衰减。随着Darcy-Forchheimer参数的增大,热廓线增大。曲率参数越高,速度分布越明显,热分布越明显。这项独特的工作可能有利于纳米技术和相关的纳米组件。Ag和CuO纳米颗粒的这种安全的尺寸控制生物合成导致了一种低成本的纳米技术,可用于各种应用。生物合成Ag和CuO颗粒已成功地应用于各种应用,包括生物医学,抗菌剂,生物,食品安全和生物传感等。

Comparative investigations of Ag/H2O nanofluid and Ag-CuO/H2O hybrid nanofluid with Darcy-Forchheimer flow over a curved surface
Abstract Nanofluid performed well and produced good results in heat transport phenomena, attracting scientists to suspend other combinations of nanoparticles, called “hybrid nanofluid. Hybrid nanofluids are superior than nanofluids due to their thermal capabilities and emerging benefits that contribute to the boost in the rate of heat transmission. Applications for these nanoparticles, including sophisticated lubricants, are increasing in the fields of bioengineering and electricity. The main prospective of this research is to inquire about the water-based dual nature nanofluid stream numerical simulation through the irregular stretched sheet with heat transfer. In this perspective, silver with base fluid water is used as nanoparticles for nanofluid, and for making hybrid nanofluid, copper oxide and silver particles are used with water-based fluid. Modified Fourier and Fick’s model for heat flux utilized the above phenomenon and observed the heat and mass transport. Similarity variables are needed to transform the partial differential equations into associated nonlinear ordinary differential equations, which are then computationally resolved by the technique of bvp4c which is a built-in function in MATLAB mathematical software. Based on the concurrent approximations, reformations are performed to determine the impact of various quantities on flow variables. The predicted outcomes are depicted in velocity, temperature, and concentration profiles through graphical depiction. The factors indicate that the hybrid nanofluid is more powerful in the transfer of heat than a basic nanofluid because of its superior thermal characteristics. The velocity profile decays for the increasing values of Darcy-Forchheimer parameter. The thermal profile increases for the higher magnitude of Darcy-Forchheimer parameter. The velocity distribution profile increases for the higher values of curvature parameter, while the thermal profile decreases. This unique work might benefit nanotechnology and related nanocomponents. This safe size-controlled biosynthesis of Ag and CuO nanoparticles has resulted in a low-cost nanotechnology that may be used in a variety of applications. Biosynthesized Ag and CuO particles have been used successfully in a variety of applications, including biomedical, antibacterial agents, biological, food safety, and biosensing, to mention a few.
