摘要
基于RANS方程,采用RNGk-ε湍流模型和VOF两相流模型,研究了尾板长度与安装角度对穿浪双体船总阻力的影响规律。计算结果表明:尾板可以调整穿浪双体船的航态,达到有效降低阻力的目的;减阻在一定速度范围内有效,减阻的效果取决于尾板安装角度和长度,但阻力的减少并不与安装角度和长度成比例,最佳的安装角度约为3°～6°,长度约为1%～2%LWL。
Based on air-water two-phase RANS equations,the RNG turbulence model and VOF two-phase flow model were used to analyze the influence of the stern flap length and installing angle on the total resistance of wave piercing catamarans（WPC）.Some results are summed up as follows： the trim of WPC can be regulated by the stern flap;the reduction resistance of WPC with the stern flap is related to velocity,and the reduction effect is up to the installing angle and the length of stern flap;the optimal angle of the stern flap is about 3°~6° and the length is about（1%~2%） LWL.
