Numerical calculation and experimental study of hydrodynamic coefficients of submarine of a series of rudder and wing

操纵性水动力系数的准确计算和测量对潜艇操纵性预报及运动控制起着至关重要的作用。文中以SUBOFF为研究对象,基于切割体网格应用STARCCM+软件完成系列舵翼艇体阻力的数值模拟;采用基于三角形网格的面元法程序和循环水槽操纵性试验2种方法获得系列舵翼缩比模型(λ=2:1)的水动力系数,并研究不同Re下舵角水动力系数的变化趋势。结果与文献[1]对比,验证了STARCCM+对潜艇阻力性能模拟的可靠性以及2种方法获取水动力系数的正确性,为潜艇水动力系数的CFD数值模拟和操纵性预报仿真提供可靠的参考依据。

The accuracy and measurement of hydrodynamic coefficient for maneuverability prediction and motion control of submarine plays a vital role. For SUBOFF as the research object,based on trimmed mesh using STARCCM ＋ software to complete the simulation of the hull with a series of rudder and wing resistance. The application of panel method based on triangle grid and maneuverability test by using the circulating water channel to obtain the hydrodynamic coefficient of scale model（ λ = 2 ： 1） of a series of rudder and wing,and studied the variation tendency of hydrodynamic coefficients of the rudder angle under different Reynolds number. It indicates that STARCCM ＋ on the simulation of resistance of submarine are reliable and the two methods to obtain the hydrodynamic coefficients are correct by comparing computed results with the first literature, it also provides reliable reference for the hydrodynamic coefficients of submarine obtained by CFD numerical simulation and the maneuvering forecast simulation.
