电厂长扁圆形烟囱体型系数试验研究
Experiment investigation to bodily form coefficient of long flat roundness chimney in electricity plant
【摘要】 由于长扁圆形烟囱外形特殊,风荷载规范中没有其体型系数。为了确定长扁圆形烟囱的体型系数,作者借助了风洞试验方法。主要阐述了长扁圆形烟囱气动弹性风洞试验情况,运用试验结果推求了长扁圆形烟囱的体型系数,其计算结果可直接用于烟囱设计,填补了风荷载规范中这种体型的空白。
【Abstract】 Because shape of long flat roundness chimney is special,there is not its bodily form coefficient in wind load criterion.The author used wind tunnel simulation experiment method in order to confirm the bodily form coefficient of long flat roundness chimney.This text expatiated on gas elasticity wind tunnel simulation experiment of long flat roundness chimney,and ascertained its bodily form coefficient by the experiment result.The result can be used chimney design,and filled up blank of this bodily form in wind load criterion.
