“…Figure 1 illustrates the adopted physical domain of the parabolic trough collector. The concentrator geometry is designed according to [9,21]:

h = \frac{w^{2}}{2 f},

where h is the depth of the parabolic concentrator (m), w the with (m), and f the focal length.…”

“…It was found that the numerical investigations are more numerous than experiments due to a lower cost in performing a parametric numerical study. Serrano-Aguilera et al 8,9 used the inverse Monte Carlo tracing method to calculate the flux distribution on circular and flat receivers. Results proved that this method is very effective in improvement of the distribution of concentrated flux on the receiver.…”

In this study, the optical and thermal performance of a Parabolic Trough Collector PTC system is investigated theoretically. A series of numerical simulations and theoretical analysis has been conducted to investigate the effect of the receiver geometry and location relative to the focal line on its optical performance. The examined receiver geometries are circular, square, triangular, elliptical and a new design of circular-square named as channel receiver.The thermal performance of PTC is studied for different flow rates from (0.27 to 0.6 lpm) theoretically. Results showed that the best optical design is the channel receiver with an optical efficiency of 84% while the worst is the elliptical receiver with an optical efficiency of 70%. Thermally the best design is the elliptical receiver with a thermal efficiency of 85% while the worst is the circular receiver with a thermal efficiency of 82%.
