Opis (eng)

The work within the PhD thesis includes research and development of energy and environmental highly effective concentrating solar systems and receivers. The solar parabolic concentrator consists of a multi-segmented parabolic reflector and spiral corrugated heat absorber. Examinations of solar parabolic concentrating collectors are focused on the analysis of different concepts of solar optical concentrator, different concepts of solar receivers (absorbers), and the optimizing geometrical and optical parameters for different levels of generated power (up to 10 kW). The aim of developing this type of solar concentrator is to increase the coefficient of the concentration ratio, increase the efficiency of utilization of solar energy, increase the efficiency of converting solar energy into other forms of energy, and reduce the prices of the obtained heat, cooling or electricity. The development of the solar parabolic concentrator is based on a long-term review of the literature and analysis of a large number of different solutions. The subject of this PhD thesis is the development, design and construction of the prototype solar parabolic concentrating collector (concentrator of solar radiation plus receiver) from the aspect of the polygeneration systems. The main objective of creating this doctoral thesis is that by using modern experimental and numerical research methods perform theoretical and experimental research of solar parabolic concentrating heat collectors, and came to the optimal solution for our the conditions. Based on the obtained optimal solution was developed 3D model parabolic concentrators and numerical analysis was conducted from the standpoint of optical design concentrator solar, thermal behavior of concentrated solar radiant heat absorber, non-linear FEM analysis of the stability of the system to the impact of its own weight and wind loads. Based on the geometric and optical optimization made the final numerical model and the physical prototype of real solar parabolic concentrator that is tested in real conditions. On the basis of the experiment was performed and verification of mathematical models of the solar parabolic concentrator.
