基于聚光集热和脉动风压的定日镜群模拟研究
Simulation of heliostat group based on heat gathering and fluctuating wind pressure
摘要
Abstract
The amount of solar radiation and wind load will directly affect the continuous generation of solar thermal power station.Therefore,according to the actual environmental conditions of Zhongdian Nao Maohu solar thermal Power Station in Hami region,Xinjiang,a three-dimensional numerical model of heliostat group was established to simulate the heating conditions and flow field characteristics of the mirror group under solar radiation and upwind Angle in different seasons,and the distribution of mirror flares and pulsating wind pressure coefficients under different wind incidence angles were analyzed.The results show that the simulated drag coefficient and lift coefficient are in good agreement with the related research results,which verifies the validity of the model.The distribution of flares in different seasons is similar and mainly depends on the variation of solar direction Angle.With the increase of the wind incidence Angle,the wake region of the mirror cluster decreases first and then increases.Since the wake in the helioscope group can effectively inhibit wind pressure,the internal stability can be ensured by combining the arrangement of the group.Among them,the center of the regular pentagonal helioscope maintains a low pulsating wind pressure,which greatly improves the force balance of the mirror.关键词
