K., Multi-Mirror Array Calculations With Optical Error The optical performance of a 2-axis solar concentrator was simulated with the COMSOL Multiphysics® software. The concentrator consists of a mirror array, which was created using the application builder. The mirror facets are preconfigured to form a focal point. During tracking all mirrors are moved simultaneously in a coupled mode by 2 motors in two axes, in order to keep the system in focus with the moving sun. Optical errors on each reflecting surface were implemented in combination with the solar angular cone of ± 4.65 mrad. As a result, the intercept factor of solar radiation that is available to the receiver was calculated as a function of the transversal and longitudinal angles of incidence. In addition, the intensity distribution on the receiver plane was calculated as a function of the incidence angles. 2019 5 Link direkt zum PDF-Download: https://www.comsol.jp/paper/download/856481/200918_SCO4_Paper_COMSOL_jg.pdf 1 6 weltweit https://www.comsol.com/paper/multi-mirror-array-calculations-with-optical-error-95421 Fachbereich Energietechnik OPUS4-9101 Konferenzveröffentlichung Sattler, Johannes, Christoph, sattler@sij.fh-aachen.de; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; Caminos, Ricardo Alexander Chico, chico-caminos@sij.fh-aachen.de; Mitchell, John C., ; Ruiz, Victor C., ; Kalogirou, Soteris, ; Ktistis, Panayiotis K., ; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Dynamic simulation model of a parabolic trough collector system with concrete thermal energy storage for process steam generation 2019 NaN AIP Conference Proceedings 2126 150007-1 150007-8 10.1063/1.5117663 weltweit https://doi.org/10.1063/1.5117663 Fachbereich Energietechnik OPUS4-9100 Konferenzveröffentlichung May, Martin, may@sij.fh-aachen.de; Breitbach, Gerd, breitbach@fh-aachen.de; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; Latzke, Markus, latzke@sij.fh-aachen.de; Bäumer, Klaus, baeumer@sij.fh-aachen.de; Uhlig, Ralf, ; Söhn, Matthias, ; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Experimental facility for investigations of wire mesh absorbers for pressurized gases 2019 NaN AIP Conference Proceedings 2126 030035-1 030035-9 10.1063/1.5117547 weltweit https://doi.org/10.1063/1.5117547 Fachbereich Energietechnik OPUS4-9098 Konferenzveröffentlichung Breitbach, Gerd, breitbach@fh-aachen.de; Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; May, Martin, may@sij.fh-aachen.de; Teixeira Boura, Cristiano José, boura@sij.fh-aachen.de; Herrmann, Ulf, ulf.herrmann@sij.fh-aachen.de Analysis of volumetric solar radiation absorbers made of wire meshes 2019 NaN AIP Conference Proceedings 2126 030009-1 030009-6 10.1063/1.5117521 weltweit https://doi.org/10.1063/1.5117521 Fachbereich Energietechnik
