摘　　要：利用计算流体力学软件FLUENT对比赛用单人赛艇实船的粘性绕流进行了数值模拟,得到了不同航速下的艇体表面压力和相应的摩擦阻力系数及粘性阻力系数;对不同航速下的摩擦阻力和粘性阻力计算结果与经验公式和实验结果进行了对比,通过比较可以看出利用FLUENT软件能够快速有效地预报赛艇船体的粘性阻力和流场。Viscous flows around a 69 kg-class single person rowing used in sports competition in full scale were simulated on computation fluid dynamics commercial software FLUENT. Numerical results of total pressure and corresponding friction and drag viscous resistance coefficient at different velocity were obtained, which were compared with the estimated ones using empirical formula, and with trial results. Validity of the calculation of the software to predict the three-dimensional viscous flows and viscous resistance of single-person rowing was proved.
