针对火力发电厂烟囱群之间的风干扰效应,应用数值风洞方法完成了任意风向角下烟囱静态风压分布的测定,并求解了风压分布系数。结果表明,相对于单个烟囱,由于烟囱群的风干涉效应导致烟囱群中风压分布异常复杂,具体表现为受扰烟囱风压极值的改变及正负风压分布区的偏移变化,为进一步研究烟囱群风荷载相互干扰对体型系数的影响及改变打下了基础.
According to the wind disturbance between chimney groups in thermal power plant, the static wind pressure distribution of chimney under arbitrary wind direction angle is solved by numerical wind tunnel method, and the wind pressure distribution coefficient is solved. The results show that compared with a single chimney, the wind pressure distribution in the chimney group is extremely complicated due to the wind interference effect of the chimney group, which is manifested as the change of the wind pressure extremum of the disturbed chimney and the offset change of the positive and negative wind pressure distribution areas, The study chimney group wind load mutual interference on body size coefficient and change laid the foundation.
