NUMERICAL INVESTIGATION ON HEAT TRANSFER, FLUID DISTRIBUTION AND SOLID STRESS TO A NEW TYPE OF SOLAR FLAT PLATE COLLECTOR

摘要

For a new type of solar flat-plate collector, which is composed of planar glass plates, some of the first results of development are illustrated. In the first part of this paper the new type of flat-plate collector is introduced. A brief description of operation, heat transfer processes and radiation conversion is given. Furthermore, the advantages and disadvantages of the development in comparison to a standard flat-plate collector are discussed. In the second part simulations on heat transfer, fluid distribution and solid stress are illustrated. By using CFD (computational fluid dynamics) the aim of these first studies is to compare them to the results obtained from analytical solutions as well as an assessment of the feasibility of the concept.
