摘要

摘要在本研究中,在多孔腔中进行了(Cu和Al2O3/水)混合纳米流体流动。固体材料的热物理结构从现有文献中被用来改善基础流体的热性能。作为多孔腔的数学模型主要用于蒸馏过程,对热能的储存至关重要。磁场也垂直于流场和所检查的磁参数对流体运动的影响。相似变量用于将控制方程转换为简化的偏微分方程。该模型采用基于控制体积的有限元方法求解。流体流动的运动采用Boussinesq–Darcy力,Koo–Kleinstreuer–Li模型用于评估混合纳米流体的特性。哈特曼数、瑞利数、多孔介质中的孔隙率因子和阻力鳍的作用改善了传统流体的热分布表现。最近的结果预测,这两种不同类型的纳米颗粒加快了通过多孔腔的热传递。百分比分析表明,混合纳米流体(Cu和Al2O3/水)在改善传统流体的热分布方面表现突出。最后,还对杂化纳米颗粒进行了网格灵敏度测试,以证明结果是渐近相干的。

Cu and Al2O3-based hybrid nanofluid flow through a porous cavity
Abstract In this study, the (Cu and Al2O3/water) hybrid nanofluid flow is carried out in a porous cavity. The thermophysical structures of solid materials are used from the available literature to improve the thermal performance of the base fluid. The mathematical model as a porous cavity is mainly used in the distillation process and is vital for the storage of thermal energy. The magnetic field is also employed perpendicular to the flow field and the impact of the magnetic parameter examined versus fluid motion. Similarity variables are used to transform governing equations as simplified partial differential equations. The model is solved using the control volume-based finite element method. Boussinesq–Darcy force is employed for the motion of the fluid flow, and the Koo–Kleinstreuer–Li model is used to assess the characteristics of the hybrid nanofluids. The roles of the Hartmann number, Rayleigh number, porosity factor in the porous medium, and drag fin improve traditional fluids’ thermal distribution presentation. Recent results predict that the two different kinds of nanoparticles speed up the heat transfer through the porous cavity. The percentage analysis shows that the hybrid nanofluids (Cu and Al2O3/water) are prominent in improving traditional fluids’ thermal distribution. Finally, the grid sensitivity test is also carried out for hybrid nanoparticles to demonstrate that the results are asymptotically coherent.
