Abstract Coastal areas and seaport areas are exposed to high wind speeds which may involve risks for the ships and people working in the area. Therefore, knowledge of the microscale wind conditions is essential for safe maneuvering and mooring of ships and optimizing harbor design. In the present study, 3D steady RANS CFD simulations with the realizable k-e turbulence model are performed for the new configuration of the “IJmuiden sea lock” in Amsterdam, the largest sea lock in the world at the time of writing this article. The computed wind speed and turbulence intensity amplification factors and the local wind directions are validated with on-site measurements for the old configuration of the sea lock. For the wind speed amplification factor and local wind direction, a satisfactory agreement is obtained with 90% of CFD data within ±30% from the measured data. Conversely, for the turbulence intensity amplification factor, less satisfactory agreement is found with 74% of CFD data within ±30% from the measured data. Overall, the 3D steady RANS approach shows a sufficiently high reliability for predicting the wind conditions in the seaport area under neutral atmospheric conditions.

关于 3D 稳定 RANS 方法在预测海港区微尺度风况方面的可靠性：以艾默伊登海闸为例

摘要 沿海地区和海港地区暴露在高风速下，可能会给在该地区工作的船舶和人员带来风险。因此，了解微尺度风况对于船舶的安全操纵和系泊以及优化港口设计至关重要。在本研究中，对阿姆斯特丹“IJmuiden 海闸”的新配置进行了具有可实现 ke 湍流模型的 3D 稳态 RANS CFD 模拟，这是撰写本文时世界上最大的海闸。计算出的风速和湍流强度放大系数以及当地风向通过对旧海闸配置的现场测量进行验证。对于风速放大系数和当地风向，90% 的 CFD 数据在测量数据的 ±30% 内获得了令人满意的一致性。相反，对于湍流强度放大系数，74% 的 CFD 数据在测量数据的 ±30% 内发现了不太令人满意的一致性。总体而言，3D 稳定 RANS 方法显示了在中性大气条件下预测海港地区风况的足够高的可靠性。
