摘要
利用计算流体力学商业软件 FLUENT对一实尺度小水线面双体船 ( SWATH)数学船型的粘性绕流进行了数值模拟 ,得到了不同航速下的船体表面总压力、表面剪切应力分布和相应的粘性阻力系数 ;将各航速下的粘性阻力计算结果和经验公式估算结果作了比较 ,验证了 FLUENT用于计算小水线面双体船三维粘性流和粘性阻力的有效性 .
In this paper the viscous flows around a mathematical SWATH in full scale are simulated based on the computational fluid dynamics commercial software FLUENT. The numerical results of total pressure, wall shear stress and the corresponding viscous resistance coefficient at different velocity are obtained. The computational viscous resistance coefficients are compared with the estimated ones using empirical formula. The validity of the software to predict the three dimensional viscous flows and viscous resistance of SWATH is proved.
