摘要

由于曾经负担得起的化石燃料供应的减少,对可再生能源的研究正在优先考虑。利用太阳能进行被动制冷和供暖可以显著减少对一次能源的需求。在这个调查中,我们看看如何改变一些变量可能会影响太阳能空气加热器的功能。它可以帮助研究人员更多地了解这些系统的发展、特性和潜在用途。本研究通过对现有文献的分析,强调热性能的价值。着重从层流亚层的形成和提高传热系数两方面探讨了提高太阳能空气加热器效率的途径。通过对几篇文章的回顾,确定了肋面粗糙度元素及其几何特性对提高太阳能空气加热器的热性能起着重要作用。相对粗糙度高度、俯仰、攻角和宽度都是需要考虑的重要因素。

Comprehensive review of key parameters for improving the performance of Solar Air Heaters
Due to declining supplies of once-affordable fossil fuels, research into renewable energy sources is being prioritized. Using solar energy for passive cooling and heating can significantly reduce the demand for primary energy sources. In this survey, we look at how changing a few variables might affect how well a solar air heater functions. It helps researchers learn more about these systems’ development, properties, and potential uses. This research analyses the current literature to emphasize the value of thermal properties. Focusing on laminar sublayer creation and increasing the heat transfer coefficient, it explores ways to increase the efficiency of solar air heaters. After reviewing several articles, it has been determined that rib roughness elements and their geometric characteristics play a significant role in enhancing the thermal performance of solar air heaters. The relative roughness height, pitch, angle of attack, and width are all important factors to consider.
