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.

储罐在炼油厂中成组布置。此外，风可被视为此类结构的临界横向载荷。本研究探讨了储罐邻接对风压变化的影响。采用风洞试验获得了升跨比为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。为了评估邻接效应，研究了横向和纵向相邻的两个储罐以及纵向和横向邻接的基础储罐。将风压系数与非相邻场景进行比较。结果发现，在距离分别是直径的三倍和四倍的横向和纵向邻接场景中，邻接效应低于 10%。发现波纹板罐的负（吸）压系数小于单板罐。
