Abstract

This paper aims to investigate the effect of using a side mirror on the north side of the field and tilting the field to the south on the efficiency of a short-length Linear Fresnel Reflector based on tentative information. Taking into account the design parameters, a prototype with specific dimensions was designed and built. The performance of the device was evaluated under different conditions. The effect of flow rate on the efficiency of the device was examined and it was found that due to the existence of vacuum tubes, increasing the discharge has little effect on the overall efficiency of the device (less than 1%). It was recommended to use a side mirror in the northern part of the field aimed at reflecting again the lost sun rays and consequently increasing efficiency by 6% compared to a field without a side mirror. Based on the experiments, it was concluded that tilting the field to the south improves the performance of the short-length Linear Fresnel Reflector by about 2.5% and 5% for tilt angles of 3 and 6 degrees respectively. Moreover, the simultaneous use of a side mirror on the north side of the field and tilting the field to the south were investigated, which revealed that the use of a side mirror on lower slopes has a greater impact on efficiency.

考虑到场坡和侧镜影响的短长线性菲涅尔反射镜总效率的实验和数值研究

本文旨在根据初步信息，研究在光场北侧使用侧镜和将光场向南倾斜对短长线性菲涅尔反射镜效率的影响。考虑到设计参数，我们设计并制造了一个具有特定尺寸的原型。在不同条件下对该装置的性能进行了评估。研究了流量对设备效率的影响，发现由于真空管的存在，增加放电量对设备的整体效率影响很小（小于 1%）。建议在电场北部使用一面侧镜，目的是再次反射失去的太阳光，从而使效率比没有侧镜的电场提高 6%。根据实验得出的结论是，在倾斜角为 3 度和 6 度的情况下，向南倾斜田地可使短长线性菲涅尔反射镜的性能分别提高约 2.5% 和 5%。此外，还研究了同时在反射场北侧使用侧反射镜和将反射场向南倾斜的情况，结果表明，在较低的斜坡上使用侧反射镜对效率的影响更大。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
