Parabolic trough solar collectors (PTCs) are among the most cost-efficient solar thermal technologies. They have several applications, such as feed heaters, boilers, steam generators, and electricity generators. A PTC is a concentrated solar power system that uses parabolic reflectors to focus sunlight onto a tube filled with heat-transfer fluid.
Therefore, for the purpose of optimizing the tracking mode of the parabolic trough concentrating collectors, the current work applied Hottel’s clear-day radiation model with an aim to study the amount of direct solar radiation received by the parabolic mirror within a year under different tracking modes in Shanghai.
The receiver, which is the heat collection element (HCE), is a black pipe located at the trough's focal line that receives the concentrated solar energy and converts it into heat, as depicted in Fig. 1. When a solar beam falls on the trough, it is reflected to the receiver at which the heat transfer fluid is located.
Depending on the number of tracking axes, the tracking modes of parabolic trough concentrating collectors can be classified as dual-axis and single-axis solar tracking modes.
General fluid dynamics software can also be used for PTC simulations, such as Sol Trace, MCRT-code/Fluent, STAR-CCM+, TracePro, or MSC Nastran. In the present work, the optical efficiency of parabolic trough solar collectors is accurately predicted by validating the proposed models using experimental data from Bellos.
Solar tracking systems commonly utilize the shadow effect idea, but it has been demonstrated that artificial intelligence-powered image processing may achieve higher accuracy. In addition, hydraulic rotary actuators are preferable to traditional step reduction gearboxes for superior tracking precision in significant solar fields.
