Abstract - The objective of this study is to optimize the
crucial for heat absorption, features varying diameters (2.5 cm to 5 cm) and is often surrounded by a concentric glass cover with a specified annular space. Reflectors, pivotal for optical efficiency, are commonly crafted from materials like highly polished glass, aluminum foil, stainless steel, acrylic mirror, or borosilicate glass. Materials such as aluminum, stainless steel, and copper are preferred, often coated with a selective surface to optimize energy absorption and minimize heat loss. Circulation of the working fluid within the absorber tube, typically done via pumps or blowers, prevents localized overheating. Tracking mechanisms, crucial for directing sunlight onto the absorber surface, range from manual to automatic adjustment systems based on concentration ratios. Conventional fluids like synthetic oil, water, or air are commonly utilized in PTSC-based systems.
design parameters of a parabolic trough solar collector system to maximize its thermal efficiency. Specifically, the project aims to investigate the impact of various factors such as aperture area, geometrical concentration ratio, absorber tube diameter, and tracking mechanism on the performance of the collector. The parabolic trough solar collector, with its wide temperature range up to 400°C, is pivotal in concentrated solar power technology. Key Words: Parabolic trough solar collector (PTSC), Aperture area, Rim angle, Aperture width, Trough length, Thermal losses.
1.INTRODUCTION The parabolic trough solar collector (PTSC) has garnered significant attention among researchers due to its adaptable temperature range, cost-effectiveness, and established commercial status.
