ABSTRACT

In this study, the effect of the constant magnetic field (MF) on the convective heat transfer characteristics of Fe3O4/H2O ferro-nano-fluid with different nano-fluid volumetric concentrations (1.0%, 2.0%, and 5.0%) flowing in a circular pipe has been studied experimentally. Experiments have been conducted under laminar flow regime (1000≤ Re≤2300). Based on the experimental data, a good agreement has been found with the results and the well-known correlations in the literature. Also, it was obtained that increasing flow rate let to increase in Nusselt number. One of the most important results obtained is that the presence of MF offers up to 8.32% convective heat transfer enhancement compared with the absence of a MF. In addition, the constant MF applied externally to the flow is a key factor to control the convective heat transfer for such kind of geometry, which is widely used in thermal engineering systems.

MHD流动对圆管内铁纳米流体水热特性的影响

摘要

本研究研究了恒定磁场(MF)对不同纳米流体体积浓度(1.0%、2.0%和5.0)的Fe 3 O 4 /H 2 O铁纳米流体对流传热特性的影响。 %)在圆管中流动已经进行了实验研究。实验在层流状态下进行(  1000≤Re≤2300)。根据实验数据,结果与文献中众所周知的相关性有很好的一致性。此外,还发现增加流速会使努塞尔数增加。获得的最重要的结果之一是,与不存在 MF 的情况相比,MF 的存在可提供高达 8.32% 的对流换热增强。此外,外部施加到流动的恒定MF是控制这种几何形状的对流换热的关键因素,这种几何形状广泛应用于热工程系统。
