Artificial Soiling, Chamber, DepositionAbstract
This work introduces a new indoor method for the artificial soiling of solar reflectors, employing a closed-loop wind tunnel chamber to replicate controlled deposition methods in a laboratory setting. The experimental setup includes dispersing a constant dust amount and allows manipulation of deposition to examine the impact of airflow speeds (1, 3, and 4.5 m/s), dust concentration and various humidity levels. The results show significant improvements of artificial soiling deposition, leading to more uniform deposition on the mirror surfaces and allowing a repeatable test.
