本文研究了由快速排水量船舶模型（INSEAN模型2340）在波浪破碎的情况下所产生的船首波下的流动结构。获得的数据也用于CFD验证的详细数据库。用手指探针测量了波高的均值和均方根值。将破碎波的强度作为波高的均方根值。利用5孔皮托探针，在前垂直线下游0.15 LPP和0.2 LPP处测量了自由表面下的平均速度场。波高和速度场结果的不确定度评定按照AIAA标准S-071-1995进行。本文给出了基于破碎模型的RANSE代码的CFD初步计算结果与实测数据的对比。
We investigated the flow structures under the bow wave generated by a fast displacement ship model (INSEAN model 2340) in the presence of wave breaking. The data acquired were also used for a detailed database for CFD validation. The mean and r.m.s. point-wise values of the wave height were measured by means of a finger probe. The intensity of the breaking wave was taken as the r.m.s value of the wave height. The mean velocity field under the free surface was measured at 0.15 LPP and 0.2 LPP downstream of the fore perpendicular by means of a 5-hole Pitot probe. Uncertainty assessment of the wave height and velocity field results was performed following the AIAA Standards S-071-1995. Preliminary CFD results from a RANSE code with a breaking model are shown in comparison with the measured data.
