دراسة عددية لتقييم تأثير الزعانف الداخلية على أداء المجمع الشمسي ذي الصندوق المسطح

Abstract

This paper presents a numerical study to improve the performance of a flat-box solar collector using internal fins as flow turbulence generators. Numerical simulations were performed using ANSYS Workbench (CFD fluent), The study area consists of water (fluid domain) and a metallic aluminum collector structure (solid domain). The study compared the effects of longitudinal, transverse, and perforated fins on fluid flow and temperature distribution in the collector. The results show that fin orientation has a significant effect on flow turbulence and outlet temperature along the collector. Perforated transverse fins exhibit improved performance relative to outlet temperature.
