摘　　要：应用数值计算方法对含有全部附体地效翼船粘性绕流进行计算分析。根据地效翼船的复杂几何特性,构造网格的特有的分块形式,采用标准k-ε湍流模型计算了XTW 4地效翼船巡航状态空气绕流流场,同时将计算得到的结果与实验值进行对比,吻合较好。The uncompressive viscous flows around wing-in-ground-effect craft XTW4 with attached parts are studied by the modern numerical method. According to different geometrical characteristics of the wing in ground effect craft and connection ways of different complicated shapes of bodies, different grid partition methods are adopted. Using standard κ-ε turbulence model, the viscous flow field around the craft is numerically computed. The numerical simulation results are in good agreement with experimental data.
