摘要

本文总结了SNAME OC-8 CFD工作组正在进行的工作,为CFD模拟的风荷载估计提供指导。该指南的目的是帮助业界利用CFD技术获得海上浮式设施风荷载的可靠和准确估计,以实现稳定性、整体性能和系泊分析。指南的起点是由Task Force的10个参与者共同开发的CFD建模实践。通过CFD模拟,对具有简化上部结构的半潜船进行了风荷载盲验证。通过对各参与者独立CFD模拟的风荷载进行比较,证实了CFD能够提供可靠、准确的风荷载,在模拟(或试验)设置上比风洞试验的不确定性更小。提出了基于CFD建模实践的指导方针发展路线图。

Developing Industry Guidelines for the CFD-Based Evaluation of Wind Load on Offshore Floating Facilities
This paper summarizes an on-going effort by SNAME OC-8 CFD Task Force to provide guidelines on wind-load estimation by CFD simulation. The intention of the guidelines is to help the industry to obtain reliable and accurate estimations of wind load on offshore floating facilities using CFD technology, for the purposes of stability, global-performance and mooring analyses. The starting point of the guidelines is CFD modeling practices collectively developed by ten participants of the Task Force. Blind validation of the wind loads from CFD simulations has been made for a semisubmersible with simplified topsides geometry. Comparison of the wind loads from independent CFD simulations from the participants confirmed that CFD can provide reliable and accurate wind load with fewer uncertainties in the simulation (or test) set up than wind-tunnel testing. A roadmap to develop the guidelines based on the CFD modeling practices is proposed.
