中文摘要：
针对某轮式两栖车辆,采用k-ω湍流模型和Level Set多相流处理方法对两栖车体绕流场进行数值模拟.通过与试验结果的对比,验证了数值方法的可行性,并对比了基础车型与加装尾翼板和防浪板的车型在不同工况下的航行阻力特性.研究结果表明：对于轮式两栖车辆,尾翼板减阻与Fr密切相关.当Fr＜2.087时,加装尾翼板能够起到较好的减阻效果;当Fr＞2.087时,加装尾翼板反而起到增阻作用,此时需收起尾翼板.
英文摘要：
Numerical simulation of the flow fields around a wheeled amphibious vehicle is carried out by using the k -to turbulence model and the Level Set method of multiphase model, Computational results are consistent with the experimental data. The function of its empennage on the vehicle is analyzed. The results show that the empennage can effectively reduce both the sailing angle of the vehicle and its sailing resistance when Fr is less than 2. 087, and that the empennage should be packed up while Fr is greater than 2. 087 because additional resistance is brought about to the amphibious vehicle.
