Influences of installation and tracking errors on the optical performance of a solar parabolic trough collector

Abstract: a b s t r a c tThe parabolic trough collector is an important component of parabolic trough solar thermal power generation systems. Coordinate transformations and the Monte Carlo Ray Trace (MCRT) method were combined to simulate the circumferential flux distribution on absorber tubes. The simulation model includes the optics cone with non-parallel rays, geometric concentration ratios (GCs), the glass tube transmissivity, the absorber tube absorptance and the collector surface reflectivity. The mode is used to … Show more

“…One is that the flow rate error will accumulate along with the results of the outlet temperature. Another one is that the installation error of the SCAs will cause the discrepancies of outlet temperature within some short periods of time [28], such as Loop 1 from 10:50 to 11:10 and Loop 3 from 10:40 to 11:00.…”

“…Additionally, it can also be estimated by means of simulation. The Monte Carlo ray tracing (MCRT) method is very flexible and has been proved to have a great accuracy: Li et al performed the MCRT simulation on a Xe-arc lamp, with results of radiation power 0.32% higher than the experiment measurement [13]; Zhao et al set up the MCRT model for the parabolic trough collector, and it had good agreement with the theoretical formula [14]. Additionally, the MCRT method is effectively used to design and optimize the parameters for a solar concentrating system [15,16].…”
