各国大型冷却塔塔筒表面风压实测对比及展望

On comparison of wind pressure measurements of tube surface at large cooling towers in different countries and its prospect

介绍了文献可查各国大型冷却塔塔筒表面实测平均风压系数、脉动风压系数、塔筒内表面风压系数,并结合现有规范进行了对比分析,指出有必要进行全方位的冷却塔表面风荷载实测,以完整再现冷却塔表面风荷载绕流特性。

The paper introduces the average wind pressure coefficient,fluctuating wind pressure coefficient,surface wind pressure coefficient in the tower tube of the tube surface of large cooling towers in different countries which can be found in literature,undertakes the comparative analysis by combining with the existing regulations,and points out the whole-sided measurement of the surface wind loading of the cooling towers,so as to reflect the streaming features of the surface wind loading capacity.
