| 摘 要： | 本文使用RANS方程和剪切应力输运k-ω模型求解含附体的水面船舶粘性流场.整个计算域被分成很多区块,各个区块单独生成结构化网格,在包含不同附体部件的区块之间,网格是不匹配的,交界面处各流场变量由插值计算传递.计算中没有考虑自由液面的影响.从最后计算得到的桨盘面伴流分布结果来看,数值计算较好地反映了桨盘面流场的特征.

| Abstract: | RANS equations and shear stress transport k-w turbulent model was used to solve viscous flow around a ship with appendage.The whole computational domain was divided into many blocks each with different appendage.Non-matching structured grid was generated in each block.Variables of flow field across interface boundary are interpolated.Free surface effect was not considered in this computation.The predicted velocity distribution at propeller disk shows that the numerical result is in good agreement with experiment. |
