摘　　要：利用商业CFD计算软件FLUENT,在不考虑自由液面情况下,对某低速肥大型船进行粘性流数值模拟,得到在不同傅氏数下的船体摩擦阻力系数及船体周围流场信息,通过把数值模拟计算的摩擦阻力系数和经验公式相比较,验证了FLUENT用于预报三维船体摩擦阻力的有效性,所得到的船体周围的流场信息可以为线型的优化提供一定的参考数据。By using CFD software FLUENT, without considering the free surface, numerical simulation of viscous flow is made for a low-speed full form to obtain friction resistance coefficients under different Fround number and flow field information around hull. After comparing the friction resistance coefficients with ITTC formula, it is proved that the frictional resistance coefficients are consistent with the ITTC formula, the numerical calculation method is effective and the obtained flow field information around hull could provide reference data for optimization of ship line.
