Full-scale, wind tunnel and CFD analysis methods of wind loads on heliostats: A review

摘要

Optimum design of isolated units or fields of heliostats is depend upon obtaining realistic design wind loads. These structures may become even more sensitive to wind loads as gravity loads decrease through innovative technology. The presence of the wind affects the stability and the optical performance of the heliostat. Predicting wind loads is very important for developing heliostats with good performance. In this paper, the main analysis methods of wind loads on heliostat are investigated. The use of full-scale, wind tunnel or CFD analysis method is closely related to the parameters studied, the accuracy of results and the financial and material resources available. The comparison of methods shows that each method has its advantages and disadvantages depending on studied cases. (c) 2015 Elsevier Ltd. All rights reserved.
