Název v původním jazyce

Solar absorbers with a structured surface

Popis výsledku v původním jazyce

The article deals with the issue of a new type of solar absorbers, which have a direct flow structure and a structured surface, which consists of pyramidal cavities. This solution increases a thermal efficiency. In the first part, possible parameters that affect the thermal efficiency of solar collectors are described and further, a simulation of a dependence of a resulting absorption coefficient at a pyramidal apex angle and daytime or season is performed. For this purpose a simulation program was developed in the MATLAB software environment by using the Monte Carlo method. The second part of the paper deals with the possibilities of production of the solar absorber with the structured surface, mainly by using the pillow hydroforming technology. The production process is simulated in ANSYS software. In this case, an austenitic chromium nickel stainless steel X5CrNi18-10 is used as a material for the production of solar absorbers.
