| Popis: | The basic characteristics of a concentrator, such as the number of reflectors, their coordinates and orientation, the degree of concentration, and others are determined with the use of the optical-geometric approach depending on the configuration parameters of the concentrator. Based on the presented formulas and numerical results, it is possible to determine the parameters of an arbitrary configuration of a linear-focus concentrator with flat Fresnel reflectors located on a parabolic base. The specific features of the distribution of the energy density over the receiver are determined. The paths of solar beams in the system and formation features of the transverse focal lines of the concentrated optical radiation are graphically analyzed for the case of the exact orientation of the concentrator on the Sun. |
