Abstract

The current study investigates the steady two-dimensional (2D) hybrid nanofluid (Hnf) flow over an inclined permeable plate/cylinder. The Hnf flow has been examined in the context of mixed convection, heterogeneous/homogenous chemical reaction, and permeable medium. The Hnf is prepared by dispersing silver (Ag), and iron ferrite (Fe3O4) nanoparticles (NPs) in water. The current research is motivated by the increasing demand for highly efficient cooling devices in a variety of industries and energy-associated operations. The energy transmission and fluid flow are mathematically specified by using a coupled nonlinear system of partial differential equations (PDEs). The system of PDEs is simplified into a dimensionless form of ODEs, which are then further numerically treated with the MATLAB package based on the finite difference method (bvp4c). It has been noticed that the permeability component develops the heat transfer curve while decreasing the flow rate of the fluid. The impact of heat source/sink increases the energy profile. Moreover, the plate surface demonstrates the dominant behavior of energy transportation than a cylinder with the variance of Ag-Fe3O4-NPs.

具有同质和异质化学反应的混合纳米流体流过倾斜透水圆筒/板的数值模拟

本研究探讨了二维（2D）混合纳米流体（Hnf）在倾斜透水板/圆筒上的稳定流动。在混合对流、异质/同质化学反应和可渗透介质的背景下对 Hnf 流进行了研究。Hnf 是通过在水中分散银（Ag）和铁氧体（Fe3O4）纳米粒子（NPs）制备的。当前研究的动机是各种工业和能源相关作业对高效冷却设备的需求日益增长。通过使用耦合非线性偏微分方程（PDEs）系统，对能量传输和流体流动进行了数学说明。PDE 系统被简化为无量纲形式的 ODE，然后使用基于有限差分法 (bvp4c) 的 MATLAB 软件包对其进行进一步的数值处理。我们注意到，在降低流体流速的同时，渗透率成分会使传热曲线发生变化。热源/散热器的影响增加了能量曲线。此外，在 Ag-Fe3O4-NPs 的作用下，板表面比圆柱体在能量传输方面表现得更为突出。
