Abstract:
A series of models for parabola of solar parabolic trough collector with tubular receiver were built based on cone optics method and sun shape model, such as optical concentration ratio, optical efficiency, coefficient of error, consumption of reflector materials and radius of curvature. The results show that the maximum critical concentration ratio is 68. 45, the maximum theoretical concentration ratio is 215. Compared with traditional collectors, the error factor of new collector reduces by 8. 2%, the length factor increases by 16. 8%, the curvature factor reduces by 10. 6%. These models can by the guidance for selecting the parabola for a solar parabolic trough collector.
