Wind Pressure Distribution on Through Concentrator
Abstract
Aiming to get a precise understanding of wind pressure distribution on trough concentrator surface, wind tunnel experiments on trough concentrator model were carried out in HD-3 atmospheric boundary layer wind tunnel at Hunan University in this study. The length scale of the trough concentrator was 1:15, and 324 measuring taps were arranged symmetrically on both sides, with 162 taps on each. The distribution contours of mean wind pressure coefficient and fluctuating wind pressure coefficients on mirror surface under typical working conditions were obtained. The variation of mean wind pressure coefficient of some taps with yaw angles and pitch angles were provided. Extreme wind pressure was calculated by Hermite moment-based method, and the extreme wind distribution was also presented in this article.
