摘　　要：利用流体软件FLUENT,对某三维船体的粘性绕流进行数值模拟,得到在不同航速下,在不考虑自由液面情况时船体摩擦阻力系数,通过把计算结果和经验公式相比较,验证了FLUENT用于预报三维船体摩擦阻力的有效性.Numerical simulation to viscous flow about a 3-D hull is carried out by using the famous fluid software FLUENT Through the simulation, we get frictional resistance coefficient at different speeds when we don＇t consider the condition of free levels. Through comparison results with experiential formula, it is provedthat the software FLUENT is effective in the field of predicting friction resistance of a 3D ship.
