Parabolik Oluklu Solar Kollektörlerin Termal Verimliliğinin Artırılması: Genel Bakış

This article examines various methods to enhance the thermal efficiency of parabolic trough solar collectors (PTCs), both theoretically and experimentally. These include increasing surface area absorber tube increase its ability absorb energy, placing a inserts inside induce turbulence hence improve heat transfer. Among other are also minimization reflection by using selective coatings on tube. Additionally, conductivity working fluid, or modifying altering shape reflective have been shown improved performance minimizing energy losses due conduction, convection, radiation. All these similar approaches that address system parameters lead performance, but they entail pressure drop cost system. In this study, techniques used PTCs addressed presented in detail along with findings previous studies.
