石化类框架式高塔设备是一种由框架和高塔组合所形成的特殊高耸风敏感结构。本文采用CFD技术对其进行了计算风洞试验数值模拟,获得了此类组合结构的风压分布特征和局部与整体体型系数,并与规范和相关文献资料进行了对比,研究分析了组合结构中框架与塔的风压相互干扰作用。模拟结果和分析表明,框架和塔体之间在不同风向角的作用下,两者之间均存在着相互干扰影响;0。风向角下塔体的体型系数为0.50,框架为1.79,整体体型系数为1.08;45。风向角下塔体的体型系数为0.37,框架为1.74,整体体型系数为1.23。在45。风向角下框架和塔体之间的风压干扰影响为最大。
Petrochemical framework type tower equipment is a tower and the tower by the combination of the formation of a special towering wind sensitive structure. In this paper, CFD technology is used to calculate the wind tunnel test numerical simulation, wind pressure distribution characteristics and local and overall body coefficient of such composite structures are obtained, and compared with the normative and related literature data, Wind pressure of frame and tower interfere with each other. The simulation results and analysis show that under the action of different wind direction angles between the frame and the tower body, mutual interference exists between the two. Wind body angle tower body factor of 0.50, the framework of 1.79, the overall size factor of 1.08; Wind body angle tower body factor of 0.37, the framework of 1.74, the overall body factor of 1.23. At 45. The influence of wind pressure interference between the frame and the tower under the wind direction angle is the greatest.
