SOLAR ABSORBER WITH A STRUCTURED SURFACE – A WAY TO INCREASE EFFICIENCY
Autor: Libor Mrňa, Jan Řiháček, Martin Šarbort, Petr Horník
Publikováno v: Acta Polytechnica, Vol 59, Iss 2, Pp 134-143 (2019)
The basic idea of a solar absorber’s thermal gain increase is the keyhole effect utilization during which the radiation is absorbed by multiple reflections on cavity walls. The lattice of pyramidal or conical cavities on the solar absorber surface

MANUFACTURING OF SANDWICH PANELS AND ITS VERIFICATION BY NUMERICAL SIMULATION
Autor: Libor Mrna, Jan Rihacek, Martin Harant
Publikováno v: MM Science Journal. 2021:4797-4802
This paper deals with the manufacturing of a parallel hydroformed sandwich panel, which is used as a reinforcement for solar panels. The forming process can cause excessive thinning and cracking. Therefore, PAM-STAMP software is used for the analysis
