摘要
针对大型邮轮艏侧推进器引起的有害振动与噪声问题,对艏侧推进器孔内流场进行数值模拟。从控制方程和控制方程求解两方面论述数值计算理论基础,进行网格划分和计算设置,并分析在左舷转向工况和右舷转向工况条件下艏侧推进器孔内的轴向速度和压力分布。根据分析结果,对艏侧推进器孔进行设计优化。
In view of the problem of harmful vibration and noise caused by the bow thruster of large cruise ship,a numerical simulation of hole flow field in bow thruster is performed.The theoretical basis of numerical calculation is discussed in control equation and control equation solution,the meshing and calculation settings are performed,and the axial velocities and pressure distributions in bow thruster hole under port steering operation condition and starboard steering operation condition are analyzed.Based on the analysis results,the design optimization of the bow thruster hole is performed.
