摘要

以一定日镜场为研究对象,通过镜场缩尺模型测压风洞试验,在代表性工况下获取各布置位置镜面的压力系数分布,计算镜场中不同位置定日镜的风振系数,综合讨论俯仰角和风偏角对不同位置定日镜风压系数和风振系数的影响。结果表明,定日镜场不同位置处定日镜的风压系数和风振系数的分布规律表现出典型的“区域性”：可将整个镜场定性分为边缘镜场和内部镜场两个区域进行直观总体把握。并发现在特定的风偏角作用下,部分内部镜场特定位置处的定日镜风振系数显著降低,表现出典型的“角落效应”。最后,基于定日镜风振系数与风压系数的高度相关性,提出一个可快速估算不同位置处定日镜风振系数的经验公式。

Abstract

A heliostat field is selected as the research object. Spatial distributions of surface pressure coefficients of heliostat surfaces at different positions within the field under typical working conditions are obtained through a wind tunnel test on a scaled model of the heliostat field. Wind vibration coefficients of heliostats at various positions in the field are calculated, and the effects of pitch angle and wind deviation angle on these coefficients are comprehensively discussed. The results indicate that the distribution patterns of wind pressure and wind vibration coefficients at different positions exhibit a characteristic “regional” feature. The entire field can be qualitatively divided into two regions： the edge field and the inner field, for an intuitive overall understanding. It is also found that under specific wind deviation angles, the wind vibration coefficients at certain positions within the inner field significantly decrease, exhibiting a characteristic “corner effect”. Finally, based on the strong correlation between wind vibration and wind pressure coefficients, an empirical formula for the rapid estimation of wind vibration coefficients at different positions is proposed.
