Abstract

In this paper, a comprehensive review has been carried out on the natural convective heat transfer inside various cavities containing nanofluid affected by the magnetic field (M.F). First, an introduction has been presented on the nanofluids and their applications, and then the magnetic nanofluids and the numerical studies on them have been finally evaluated. Nanofluid numerical studies under the effect of the M.F are modeled in two states: single-phase (S.P) and two-phase. A S.P model is assumed without any slipping between the fluid and nanoparticles. But in the two-phase model, the particle slip and motion of the particles are considered. In fact, in this study, the classification of papers with a common geometry and effective parameters on the nanofluid exposed to the free convection and M.F effects of has been studied. According to the results obtained by the researchers, it can be concluded that the rate of heat transfer decreases by enhancing the M.F and reducing the volumetric fraction of the nanoparticle and reducing the buoyancy force.

研究各种参数对暴露于磁场的各种空腔中纳米流体的自然对流的影响：综述

摘要

在本文中，已经对包含磁场（MF）影响的包含纳米流体的各种腔体内的自然对流换热进行了全面的综述。首先介绍了纳米流体及其应用，然后对磁性纳米流体及其数值研究进行了最终评估。MF影响下的纳米流体数值研究以两种状态建模：单相（SP）和两相。假设采用SP模型，流体和纳米颗粒之间不会发生任何滑动。但是在两相模型中，考虑了颗粒的滑移和运动。实际上，在这项研究中，已经研究了具有共同几何形状和有效参数的纳米流体在自由对流和MF效应作用下暴露的论文的分类。
