Abstract

Storage tanks are placed in group arrangements in refinery plants. Furthermore, winds may be treated as a critical lateral load for such structures. The present study explores the effects of storage tank adjacency on wind pressure variations. The wind tunnel test was employed to obtain the wind pressure coefficients on corrugated-plate tanks with rise-to-span ratios of 0.25, 0.5, 1.0, and 1.5. These coefficients were also calculated numerically through a computational fluid dynamics (CFD) approach and compared to the experimental data. To evaluate the adjacency effect, two adjacent tanks in the transverse and longitudinal directions and the base tank with longitudinal and transverse adjacency were studied. The wind pressure coefficients were compared to the non-adjacency scenario. It was found that the adjacency effect was below 10% in transverse and longitudinal adjacency scenarios at distances three and four times as large as the diameter, respectively. The corrugated-plate tanks were found to have smaller negative (suction) pressure coefficients than simple-plate ones.

基于储罐相邻关系的风对储罐影响的数值和实验研究

炼油厂的储油罐是成组布置的。此外，风可以被视为此类结构的关键侧向荷载。本研究探讨了储油罐相邻位置对风压变化的影响。通过风洞试验获得了上升跨度比为 0.25、0.5、1.0 和 1.5 的波纹板储罐的风压系数。这些系数还通过计算流体动力学（CFD）方法进行了数值计算，并与实验数据进行了比较。为了评估相邻效应，研究了横向和纵向相邻的两个水箱以及纵向和横向相邻的底座水箱。风压系数与非相邻情况进行了比较。结果发现，在横向和纵向相邻的情况下，相邻效应在距离分别为直径的三倍和四倍时低于 10%。研究发现，波纹板水箱的负（吸）压力系数小于简单板水箱。
