Experimental Set-Up for Investigation of Air-Flow and Dust Deposition in Heliostat Field: Design and Evaluation
Abstract
In this paper, design and evaluation of an experimental setup for analyzing air-flow and to understand dust deposition on heliostats in a field-layout is presented. For this purpose, a heliostat field is designed and air-flow is investigated for the selected staggered arrangement of heliostats. The evaluation clearly revealed the presence of flow separation and wake behind an inclined heliostat models. Such complex flow field will affect dust deposition on heliostat and may even induce vibration. Hence, experimentation would be necessary to investigate the flow field in these regions. The developed experimental set-up based on detailed flow analysis will be useful for understanding the dust deposition and wake induced vibration of heliostats in field layout.
