Study on optical and thermal performance of a linear Fresnel solar reflector using molten salt as HTF with MCRT and FVM methods

“…1 and y m is the y-value of the mirror's axis, R te is the tracking error of the mirror and R te $N(0, r 2 te ), a and F are the solar altitude and azimuth, respectively, which can be calculated with the local latitude u, solar time t s , and the number of the day in a year N day [31].…”

“…The system is designed, and a 3D optical model is fully developed with Monte Carlo Ray Tracing (MCRT) method in order to simulate the radiation transmission within the system. The MCRT method has been utilized successfully to investigate the performance of PTCs [20][21][22], Parabolic Dish System [23][24][25], and Solar Power Tower System [26][27][28][29][30][31]. Based on the model, firstly, the local solar flux distribution on the absorber surface and the optical efficiency are computed.…”

Thermal performance analysis of a parabolic trough solar collector using supercritical CO2 as heat transfer fluid under non-uniform solar flux

“…The concentrating solar power generation (CSP) technology which produces electricity by concentrating solar energy has become a promising choice for utilizing this renewable energy and solving the environmental problems [5,6]. The parabolic trough collector (PTC) technology is the most mature one among the four main CSP technologies which are PTC [7,8], solar power tower [9][10][11], parabolic dish [12,13], and linear Fresnel reflector technologies [14].…”
