Anyway, with f = 0 and changing the receiver height from 2 m to 6 m contributes, besides the augmentation of the spot size over the receiver, to the increase of the optical efficiency of the system up to 10%. Nevertheless, this WIN 64338 could be an obstacle to avoid higher manufacturing costs. This may be overcome by choosing a convenient curvature and receiver height. When choosing curved heliostats with deflection gap of [0.2mm-3 mm] and receiver height between 2 m and 3 m we obtain an optical efficiency value which is 5% lower than the respective value when using a 6 m receiver height. This would be appropriate for small and medium power scale LFR solar field. Furthermore, using deflections close to 3 mm will allow decreasing the size of the receiver.
In this work, a numerical study has been conducted to investigate the impact of mirror curvature on optical performances of a LFR solar field installed recently in Morocco. The numerical simulations have been processed using the Monte Carlo-ray tracing simulation tool OPSOL. The code was developed to model the optical behavior of the CLFR and used to investigate the optical behavior of the system versus mirror deflection and receiver height above heliostats level. In order to assess the accuracy of the numerical code developed and examine the precision of the simulation results, a set of verification tests was conducted. Then, OPSOL is gene pool corroborated via numerical simulation results obtained by SOLTRACE code. Good agreement between results obtained within both codes is shown; the maximum average relative error for all simulations didn\'t exceed 2%.
