摘要

本文对各种类型的平板太阳能集热器的气动和热行为进行了比较研究。研究以计算流体动力学（CFD）为基础，解决了带有不同类型挡板的湍流气流问题。研究了四种型号的平板太阳能集热器：带倾斜挡板的太阳能集热器（SCIB）、带拱形挡板的太阳能集热器（SCAB）、带垂直挡板的太阳能集热器（SCPB）和带迷宫挡板的太阳能集热器（SCMB）。挡板的存在减少了流道表面积，导致气流速度显著增加，SCIB、SCAB、SCPB 和 SCMB 的气流速度分别达到入口速度的 254%、266%、290% 和 502%。

Computational 3D Simulations of Fluid Dynamics and Comparisons of Heat Transfer Characteristics of Various Flat-Plate Solar Collectors

This article presents a comparative study of the aerodynamic and thermal behavior of various types of flat-plate solar collectors. The study is based on computational fluid dynamics (CFD) which solves turbulent airflow with different types of baffles. Four models of flat-plate solar collectors were investigated: solar collectors with inclined baffles (SCIB), solar collectors with arched baffles (SCAB), solar collectors with perpendicular baffles (SCPB), and solar collectors with a maze of baffles (SCMB). The reduction in flow passage surface area due to the presence of baffles results in significant increases in airspeed, reaching 254%, 266%, 290%, and 502% of the inlet speed for SCIB, SCAB, SCPB, and SCMB, respectively.

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.
