摘    要:文章基于重叠网格技术,采用RANS方法,对2500T级小水线面双体船(带首尾鳍)的阻力与纵向航态进行了数值计算,并与模型试验结果进行了比较分析,结果表明文中采用的数值方法能够有效预报小水线面双体船的阻力,模拟其航行姿态。此外,分别对计及航态与不计及航态时的阻力计算结果进行了比较,分析了航行姿态对小水线面双体船阻力性能的影响。

关 键 词:小水线面双体船  RANS  重叠网格  总阻力

Abstract:The resistance of the 2500T SWATH (with fins) is numerically simulated by RANS approach and the overlap grid techniques. In contrast to the experimental results, it demonstrates that the numerical methods in this paper can predict the resistance of SWATH and simulate its navigation attitude well. Fur-thermore, through the comparison of numerical results of resistance of SWATH with and without considera-tion of navigation attitude, the influence of navigation attitude on the resistance of SWATH is analyzed.
Keywords:SWATH  RANS  overlap grid  total resistance
