Abstract

This present study conducted an experimental analysis of the use of hollow circular fins (HCF) within the conventional single-slope solar still (CS4) chamber. To enhance energy absorption, the optimal HCF numbers were increased by the available chamber space. The three identical CS4 testing chambers were examined in the climatic conditions of the Sebelas Maret University Faculty of Engineering, located in Kentingan, Surakarta, Indonesia. The HCF absorber is implemented with 176 HCF, 176 HCF, and 216 HCF within the chamber space. The findings indicate that there is a direct correlation between the increased HCF numbers and both productivity and efficiency. The efficiency for 117 HCF, 176 HCF, and 216 HCF is 27.04%, 35.20%, and 42.16% respectively. Therefore, it was determined that correlation analysis significantly contributed to the relationship between the HCF implementation and the different radiation intensities in day-to-day testing. To obtain a more comprehensive analysis, the randomized complete block design (RCBD) experiment in collaboration using least squares regression was conducted to compare the experimental production of CS4 with its predicted value.

中空圆鳍片在太阳能静止海水淡化中的各种实施数量的实验分析

本研究对在传统单斜太阳能蒸发器（CS4）腔体内使用空心圆形翅片（HCF）进行了实验分析。为了提高能量吸收能力，根据试验室的可用空间增加了最佳 HCF 数量。三个相同的 CS4 试验室是在位于印度尼西亚苏腊卡尔塔肯丁根的 Sebelas Maret 大学工程学院的气候条件下进行测试的。试验室空间内的 HCF 吸收器分别为 176HCF、176HCF 和 216HCF。研究结果表明，HCF 数量的增加与生产率和效率之间存在直接关系。117 HCF、176 HCF 和 216 HCF 的效率分别为 27.04%、35.20% 和 42.16%。因此，在日常测试中，相关性分析对 HCF 实施与不同辐射强度之间的关系做出了重大贡献。为了获得更全面的分析，利用最小二乘回归法进行了随机完全区组设计（RCBD）实验，以比较 CS4 的实验产量和预测值。
