摘　　要：围绕应用商业CFD软件数值模拟绕一种球鼻首、双尾丰满船型船舶周围的粘性流动问题,对该种复杂船型在GAMBIT软件中模型建立和网格划分,并将数值计算的摩擦阻力系数与1957年ITTC阻力系数公式的计算结果进行了比较,两者接近程度令人满意。The CFD software GAMBIT was applied to generate the calculation model and mesh for a full form ship with a bulbous bow and twin--stern, in order to simulate the viscous flow around the ship. The items to be pay attention in the modeling and meshing were discussed. The computed results of the frictional resistance coefficients for this ship were compared with the ITTC-1957 formula results showing that the numerical results are corresponded in a satisfied extent.
