Abstract

The study investigates the flow characteristics of spherical shaped TiO2 –Ag hybrid nanofluid with water as a base fluid passing through a wet porous rectangular moving fin with a focus on understanding the effects of nanoparticle concentration on the heat transfer rate. The fin under consideration are subjected to boundary conditions, insulated and convective tips. Hybrid nanofluid that combine nanoparticles with conventional base fluids have potentially enhanced thermal conductivity and heat transfer properties in engineering applications. The energy balance equation containing the parameters that effect the flow of heat transfer rate is non- dimensionalized and solved numerically using 3-stage Lobatto - IIIa formula with appropriate boundary conditions. The simulation result shows the impact of different parameters on the flow and heat transfer properties of the hybrid nanofluid obtained by mixing spherical shaped TiO2 –Ag hybrid nanoparticles with water as base fluid. It is observed that the fin shows significant heat transfer rate in a convective tip relative to an insulated tip. The findings contribute to the understanding of hybrid nanofluid flow and its potential application in the design and optimization of thermal management system. It also facilitates the ground work for research in the field of nano fluid based cooling system. The observation from the graphical illustration shows that the rise in the thermal conductivity of the base fluid by 23% increases the conduction heat transfer as well as the temperature distribution by 10%. The natural convection and radiation are the key parameters that determines the heat transfer rate from the surface to the surrounding. In our investigation, enhancing the Nc,Nr parameters by 50% and 25%, the temperature distribution profile is reduced by about 13% and 6% respectively. The increase in the Pe number by 100% results in a rise in the temperature distribution by 8%.

球形 TiO2- Ag 混合纳米粒子影响下的湿式多孔移动鳍片在水基流体中的性能分析
本研究探讨了以水为基本流体的球形 TiO2 -Ag 混合纳米流体通过湿式多孔矩形移动鳍片的流动特性,重点是了解纳米粒子浓度对传热速率的影响。所考虑的翅片受到边界条件、绝缘和对流尖端的影响。将纳米粒子与传统基础流体相结合的混合纳米流体在工程应用中具有潜在的增强导热性和传热特性。能量平衡方程包含影响热传导率流动的参数,采用 3 级洛巴托-IIIa 公式和适当的边界条件对其进行非尺寸化和数值求解。模拟结果表明了不同参数对混合纳米流体的流动和传热性能的影响,混合纳米流体是通过将球形 TiO2 -Ag 混合纳米粒子与水作为基础流体混合得到的。据观察,相对于绝热顶端,翅片在对流顶端显示出显著的传热率。研究结果有助于理解混合纳米流体流动及其在热管理系统设计和优化中的潜在应用。它还为基于纳米流体的冷却系统领域的研究奠定了基础。从图解中可以看出,基础流体的导热系数增加 23%,传导热量和温度分布就会增加 10%。自然对流和辐射是决定从表面向周围传热的关键参数。在我们的研究中,将 Nc、Nr 参数分别提高 50%和 25%,温度分布曲线分别降低了约 13%和 6%。Pe 值增加 100%,温度分布会上升 8%。
