本文介绍了一个新的全尺寸风墙（WoW）的风工程试验设施的设计过程。计算流体动力学（CFD）被用于初步设计的设施，随后进行的风场的实验验证与小规模的复制品。结果表明，CFD建模预测的平均风速剖面与实验测量的平均风速剖面之间具有良好的一致性，证明了CFD模拟在风工程应用中日益重要的意义。拟议中的全尺寸12风扇魔兽世界设施将能够吞没大型和全尺寸模型，以供未来测试。该设施的设计目的是产生具有适当特性的风和风驱动的雨，以模拟萨菲尔-辛普森飓风等级定义的4级飓风。新设施的目的是改善与风有关的建筑法规规定，开发创新的飓风缓解技术，并帮助加强沿海社区对飓风危害的复原力。
This paper presents the design process of a new full-scale Wall of Wind (WoW) facility for wind engineering testing. Computational fluid dynamics (CFD) was used for a preliminary design of the facility, followed by an experimental verification of the wind field conducted with a small-scale replica. Results showed good agreement between mean wind speed profiles predicted by the CFD modeling and those measured experimentally, attesting to the growing importance of CFD simulations for wind engineering applications. The proposed full-scale 12-fan WoW facility will be able to engulf largeand full-scale models for future testing. The facility has been designed to generate wind and wind-driven rain with proper characteristics to mimic hurricanes up to Category 4 as defined by the Saffir-Simpson hurricane scale. The intent of the new facility is to improve wind-related building code provisions, to develop innovative hurricane mitigation techniques, and to help strengthen the resiliency of coastal communities to hurricane hazards.
