Simulation of Fluid Flow in an Artificial Soiling Device

E. Klimm [1], S. Kochersperger [1], K.-A. Weiss [1],
[1] Fraunhofer Institute for Solar Energy Systems, Freiburg, Germany

Solar systems are used around the world, especially in sunny and dry regions, to convert radiation energy from the sun into electricity or heat. Soiling, as dust deposition onto surfaces is commonly called, hinders this conversion of the solar energy by blocking of the incidenting light. ... Read More
