摘　　要：借助STAR-CCM+软件对高速双体船深浅水绕流场进行试验和数值研究。根据深水阻力试验结果,基于国际拖曳水池会议(ITTC)规程对数值方法的有效性进行验证;对双体船深浅水绕流场进行数值模拟,并基于不同工况下的数值模拟结果对双体船浅水流场和浅水阻力进行分析。研究结果表明:高速双体船的浅水效应明显;阻力方面,剩余阻力是影响浅水阻力变化的主要成分,超临界水深工况下发生了明显的有利干扰;航态方面,双体船均出现了一定程度的艉倾和上浮;流场方面,亚临界区域的横波波长、横散波交点线夹角和散波角均随着水深的减小而增大,超临界区域仅剩散波,而散波角有明显的减小。Numerical simulations on flow around a high-speed catamaran both in the unlimited and shallow depth water are carried using STAR-CCM+software.Numerical method is verified based on experimental results according to the ITTC approach first.Numerical simulation of the flow field around the catamaran in deep and shallow water is carried out,and the shallow water flow field and shallow water resistance of the catamaran are analyzed based on the numerical simulation results under different working conditions.The research results show that the shallow water effect of the high-speed catamaran is obvious.Residual resistance is the main component that affects the change of shallow water resistance.Obvious favorable interference occurs under supercritical water depth conditions.The catamaran has a certain degree of stern and ascent.The wavelength of the transverse wave,the angle between the intersection of the transverse wave and the scattered wave angle in the subcritical region all increase with the decrease of the water depth.Only the scattered wave remains in the supercritical region,and the scattered wave angle decreases significantly.
