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.
