Large scale flow separation occurs around sails of a sailing yacht at the downwind sailing condition. In particular for the case of spinnaker, it is well known that the detailed feature of flow separation is not clear and CFD calculations do not coincide well with the measured data. In this research the detailed feature of flow separation around sails is revealed by wind tunnel tests, and the results are compared with the RANS-Based CFD calculation. The results of proposed CFD calculation method coincide well with the measured one.

帆船在顺风航行时，帆周会出现大规模的流动分离。特别是对于三角帆的情况，众所周知，流动分离的详细特征并不清楚，CFD计算与测量数据并不完全一致。本文通过风洞试验揭示了风帆绕流分离的详细特征，并与基于RANS的CFD计算结果进行了比较。计算结果与实测结果吻合较好。
