摘要
浅水中某些工程船低速、小半径回转工况作业环境复杂且操纵难度大,找出其航行受力规律,对于提高船舶航行安全性意义重大.文中采用数值方法对其作业过程进行了模拟,流体控制方程采用RANS法求解,求解器选择STAR-CCM+,模拟湍流选择k-ε模型,并用旋转坐标系法来模拟船舶的回转运动.在深水、零漂角工况下,验证了数值方法的可行性.将该法应用到较低航速下,船舶在五个不同水深、三个不同漂角和较小的半径相互组合的回转运动工况,并得到船舶所受水动力的大小及相应的变化规律.
Some engineering ships in shallow water have complex working environment and difficult operation under low speed and small radius rotation conditions.Finding out the law of their sailing stress is of great significance for improving the safety of ships sailing.The RANS method was selected to solve the governing equation,the k-εmodel was selected to simulate turbulence,and rotating reference frame was selected to simulate the ship’s rotary motion.Under deep water and zero drift angle conditions,the feasibility of the numerical method was verified.Then,the method was applied to the ship’s rotating motion under the condition of 5 different water depths,3 different drift angles and smaller radius at lower speed,and the magnitude of hydrodynamic force on the ship and the corresponding variation law were obtained.
