中文摘要：
对一典型三心圆柱面网壳进行了计算流体动力学(CFD)数值模拟,并与风洞试验进行比较,结果显示数值模拟能较准确反映实际情况,数值误差可以接受.在此基础上,将两个柱面网壳并列布置,在不同风向角及不同间距的情形下进行了详细数值模拟分析,发现此类风致干扰的主要影响因素在于遮挡效应,指出了当受扰体完全被施扰体的尾流所包裹时,遮挡效应最为严重。本文提出了柱面网壳并列布置相互干扰影响的风压分布规律和合理性建议,可指导实际工程应用。
英文摘要：
Computational Fluid Dynamics(CFD) method was first carried out to simulate a typical three-center cylindrical latticed shell in this paper.Comparison between the results from the computation and the wind tunnel test was performed,which indicated that the numerical result was closed to the practical mean wind pressure distribution.Based on this,two latticed shells were arranged in parallel,and several cases consisted of different wind angles and different space distances were made by CFD to study the wind-in...
