摘要
摘要 利用三种不同的流体(水、50:50 乙二醇-水混合物和 0.6 M 氯化钠溶液)进行了一组初步的田口设计实验,其实验结果通过尺寸分析产生了基于辐照度的相关性。实验使用了一个太阳能热水系统,该系统集成了热辐射源和平板集热器作为接收器。进行的尺寸分析包括导热液体的热物理性质、集热器接收到的辐照量以及接收器与热辐射源之间的距离。得出的无量纲相关性是雷诺数和一个新提出的无量纲数(称为 SRY 数)的函数。无量纲常数和指数是利用实验数据确定的。结果发现,提出的相关性与现有的相关性非常接近。
Evaluation of Heat Transfer Performance of Solar Water Heating System using Dimension Analysis
A preliminary set of Taguchi-designed experiments utilizing three different fluids (water, 50 : 50 ethylene glycol-water mixture, and 0.6 M sodium chloride solution) were conducted and its experimental results were used to produce an irradiance-based correlation via dimensional analysis. A solar water heating system integrated with its thermal radiation source and flat plate collector as a receiver was used for this experiments. Conducted dimensional analysis, which includes the thermophysical properties of the heat transfer fluid, amount of irradiance received by a collector, and distance between both receiver and source. The resulting dimensionless correlation was a function of the Reynolds number and a newly proposed dimensionless number, referred to as the SRY number. The dimensionless constant and exponents were determined using experimental data. The proposed correlation was found to be in close agreement with the existing correlation.
