ENERGY SAVINGS THROUGH THE USE OF BIOMIMETIC ARCHITECTURES
KOMUNALNA ENERGETIKA / POWER ENGINERING, 16
Absorbers in solar collectors are used to collect the heat from sunlight for heating and hot water production. The use of solar energy will continue to increase in the future due to the rising cost of fossil fuels such as oil and gas. The aim of this work is to optimize the pipework system in the absorber plate of a solar thermal collector in relation to uniform flow and a lower decrease in pressure for modern solar heating systems inspired by nature. The other parts of the collector like housing, insulation, and the transparent cover should be the same as in common flat plate collectors using the existing production equipment and maintaining the production line. It is essential to tag the problems of common solar panels and to define the parameters meaningful for the fluid mechanics evaluation.
The evaluation of different natural channel structures should help to find a suitable network with good characteristics in utilization and flow resistance. The chosen examples will be presented, simulated, and analyzed with appropriate software to demonstrate their flow characteristic. The resulting new pipework model will be integrated in the existing pipework design of the absorber to obtain the first bionic-optimized pipework design.
