- Abstract
Parabolic Trough Solar Collectors (PTCs) are crucial components in achieving high efficiency and thermal performance in thermoelectric power stations. This study presents a Computational Fluid Dynamics (CFD) simulation of a PTC with dimensions of 2 m × 1.5 m, incorporating a flat glass cover to safeguard the reflector's optical properties and the glass envelope from environmental factors such as dust, moisture, wind, and rain, resulting in improved thermal insulation and efficiency. A uniform temperature distribution at the Heat Collecting Element (HCE) level is assumed. A mathematical model is developed based on simplifying assumptions, and physical phenomena, including mass transfer, light, and heat, are simulated using mathematical equations derived from equilibrium equations and the optical behavior of materials (reflection, absorption, transmission). The model's validity is established through a comparison of simulation and computational results. The effects of PTC length, water mass flow, and solar tracking pattern on the water exit temperature are subsequently explored. This investigation enables the identification of optimal PTC dimensions and mass flow rates to meet the temperature requirements for various industrial and domestic applications, while maintaining high efficiency and thermal performance.
