ABSTRACT: In this paper, the dust transport and the deposition on two different solar energy systems are
studied, namely a Solar Updraft Power Plant (SUPP) and a Parabolic Trough Power Plant (PTPP). In case of
the SUPP numerical CFD-simulations were performed to study particle motion over the collector surface. A
physical wind tunnel study of asingle parabolic trough of the PTPP in combinationwith a numerical CFD-analysis
indicates for the deposition ...
