摘　　要：采用RNGk-ε湍流模型、VOF模型和PISO算法，对两栖工程车车体带自由表面的粘性绕流场进行了数值模拟，得到了该车体的粘性绕流场分布、阻力和兴波特性，计算结果与相关试验数据具有较好的一致性。在此基础上，对车体外形进行了初步优化探索，为其减阻提速的研究提供依据。The ambient flow field with free surface of amphibious engineer vehicle is numerical simulated by using the RNG k-ε turbulent flow model, the volume of fluid （VOF） model and the pressure implicit with splitting of operators （PISO） method. The distribution, resistance and wave characteristics of ambient flow field of the vehicle are computed. The computation results are well consistent with the relevant experimental results. Based on this, primary research has been done to optimize the shell of the vehicle and to provide bases for research on reducing resistance.
