摘要：
The distribution contours of mean wind pressure coefficient and fluctuating wind pressure coefficients on mirror surface under typical working conditions were obtained by conducting wind tunnel experiments on trough concentrator model. Meanwhile, the pattern and characteristics of wind pressure distribution on mirror surface were investigated; and the mean wind pressure coefficient distribution on mirror surface was studied. By focusing on fluctuating wind pressure characteristics, the factors influencing fluctuating wind pressure distribution were analyzed, and the power spectra of fluctuating wind pressure on some measuring taps were studied. The non-Gaussian characteristics of the fluctuating wind pressure measured on mirror surface were also assessed on the basis of kurtosis coefficient and skewness coefficient. (C) 2015 Elsevier Ltd.
