Abstract

Thermal solar collector considers one of the main devices employed to transform solar energy into thermal energy and can be classified into three main types named Evacuated tube collector (ETC), flat plate collector (FPC), and compound parabolic collector (CPC) collector. In this study, where it was taken to evacuated tube solar collectors three different geometries of the inner pipe diameter were proposed and combined with type of phase change materials (PCM) to evaluate their performance using PCM. And mass flow rate 0.5 L\min, A validated computational fluid dynamic (CFD) model was used in this examination. The data indicates that the highest outlet water temperature was observed at 45 ºC from 1:00 pm to 2:00 pm for case-1 with a smooth pipe, whereas for case-2 with two lobes and case-3 with four lobes, the maximum temperatures were 41 ºC and 40 ºC. respectively, The results showed that case-1 with Paraffin wax has the best efficiency among the proposed cases. Where it was recorded maximum outlet water temperature was about 45 ºC.

相变材料u型平板太阳能集热器性能的数值研究

太阳能集热器是将太阳能转化为热能的主要装置之一，可分为真空管集热器(ETC)、平板集热器(FPC)和复合抛物面集热器(CPC)三种主要类型。在本研究中，以真空管太阳能集热器为研究对象，提出了三种不同的内径几何形状，并结合相变材料(PCM)的类型来评估其使用相变材料的性能。质量流量为0.5 L\min时，采用经过验证的计算流体动力学(CFD)模型。结果表明，光滑管道case-1在1:00 ~ 2:00的出水温度最高为45℃，而管道case-2和管道case-3的出水温度最高分别为41℃和40℃。结果表明，使用石蜡处理的病例1的处理效果最好。记录的最高出水温度约为45ºC。
