摘要

流体在多孔材料中的磁流体力学(MHD)运动有多种用途,如蒸馏塔、热交换器、催化过程、基于磁场的伤口治疗、癌症治疗和热疗。本文利用介于纳米和混合(二硫化钼 [MoS2] 和多壁碳纳米管 [MWCNTs])纳米流体之间的 MHD 杰弗里流体,探讨了三相流的复杂动力学。为物理流动模型导出了控制微分方程。利用无量纲参数将这些方程简化为无量纲方程。利用常规扰动技术求解所得方程。通过二维/三维图对各种相关物理参数的结果进行分析。计算了左板和右板的传热率和体积流量。该分析还考虑了辐射和耗散效应对系统整体行为的影响。结果表明,磁参数、电参数、二次对流参数、布林克曼数和格拉肖夫数对传热增强有显著影响。利用辐射参数、孔隙率、电参数和磁参数可以降低流体速度,而杰弗里参数则会降低流体速度。

Effects of dissipation and radiation on the Jeffrey fluid flow in between nano and hybrid nanofluid subject to porous medium
The magnetohydrodynamic (MHD) movement of fluids through a porous material has a variety of uses such as distillation towers, heat exchangers, catalytic processes, magnetic field‐based wound treatments, cancer therapy and hyperthermia. This paper explores the complex dynamics of a three‐phase flow utilizing MHD Jeffrey fluid, which sits in between nano and hybrid (molybdenum disulphide [MoS2] and multi‐walled carbon nanotubes [MWCNTs]) nanofluids. The governing differential equations are derived for the physical flow model. The equations are reduced to dimensionless equations by using dimensionless parameters. The resultant equations are solved by using the regular perturbation technique. The results are analysed for various physical pertinent parameters through 2D/3D graphs. The heat transfer rate and volume flow rate are calculated for the left and right plates. This analysis also considers how the system's overall behaviour would be affected by radiation and dissipation effects. The results indicate that the magnetic parameter, electric parameter, quadratic convective parameter, Brinkman number and Grashof number significantly affect heat transfer enhancement. Fluid velocity can be reduced using radiation parameters, porosity, electric and magnetic parameters and velocity declines by Jeffrey parameters.
