摘要

研究了饱和多孔基质磁化纳米颗粒的杰弗瑞-哈默尔流动。纳米技术为增强工程设备提供了令人兴奋的新材料,其中包括电磁渗透纳米流体。采用Darcy-Forchheimer模型来定义多孔介质。研究了金属纳米粒子和氧化物纳米粒子在水中(一种基液)的性能。采用同质Tiwari-Das模型。利用MATLAB bvp4c射击法求解控制守恒方程。对没有多孔基质的清洁流体的早期解决方案进行了验证。图形化的速度可视化体现了各种参数的影响,如使用不同的纳米颗粒、固体体积分数、哈特曼数和雷诺数、两板之间的角度、多孔参数和惯性参数。结果表明,氧化硅纳米颗粒产生最佳速度,而银纳米颗粒产生最小速度。随着固体体积分数的增加,流动减少,而多孔基质的存在对流动没有明显的改变。

Jeffery-Hamel Flow in Conducting Nanofluid: Non-Darcy model
The Jeffery-Hamel flow of magnetized nanoparticles saturated with porous matrix is inspected. Nanotechnology has provided exciting new materials for enhancing engineering devices, including electromagnetic permeable nanofluids. The Darcy-Forchheimer model is employed to define the porous medium. The performance of both metallic and oxide nanoparticles is studied as they are dropped in water, which is a base fluid. The homogenous Tiwari-Das model is adopted. The governing conservation equations are solved using the MATLAB bvp4c shooting method. Verification of earlier solutions for the clear fluid without the porous matrix is conducted. Graphical visualization of the velocity is conferred for the impact of various parameters such as using different nanoparticles, solid volume fraction, Hartmann and Reynolds numbers, angle between the two plates, porous parameter, and inertial parameter. It is found that the silicon oxide nanoparticle produces the optimal velocity, and the silver nanoparticle gives the minimum velocity. Upon increasing the solid volume fraction, the flow is reduced, and the presence of porous matrix does not alter the flow remarkably.
