摘要

对超临界压力下Fe3O4-煤油纳米流体竖直管内的换热特性进行了实验研究

分析了不同压力、质量流量、热通量和纳米颗粒浓度对超临界压力下纳米流体换热特性的影响。超临界压力下

纳米流体在竖直管内沿管长呈现不同的换热规律。流体质量流量的提高或者工作压力的提高均会使纳米流体在竖直管内流动换热效果变好。而热通量的增大或纳米颗粒的添加对超临界压力下纳米流体的换热具有恶化效果。最后给出了纳米流体在超临界压力下的传热关联式

其计算值和实验值吻合良好。

Abstract

An experiment on the heat transfer characteristics of Fe3O4-kerosene flowing in a vertical upward tube at supercritical pressure was conducted. In the experiments

the effects of such factors as mass flux

heat flux

pressure and particle content were investigated. There were different heat transfer mechanisms along the tube. Increasing flow rate or working pressure could enhance heat transfer performance

but higher heat flux led to poorer heat transfer performance. Besides

addition of solid particles deteriorated heat transfer performance through modification of inner wall surface. Based on the experimental data

a correlation for predicting heat transfer of Fe3O4-kerosene at supercritical pressure was established and showed good agreement with experimental data.
