摘要
采用RNGk-ε湍流模型和VOF两相流模型,对不同尾部形状的两栖工程装备模型进行了数值模拟,得到了带有自由液面的流场分布和兴波特性。并以此为基础,分析车辆尾部形状对于航态的影响,提出减阻增速的初步设想,为进一步探索两栖工程车辆的水动力特性提供参考。
Numerical simulation of different amphibious engineer equipments＇ RNGturbulence models, two phases VOF model and multi-block hybrid meshes. characteristics of round flow field of the vehicle body are computed. Based on optimize the shell of the vehicle and to provide bases for the research on reducing round flow field is made by using The distribution,resistance and wave this, initial study has been done to resistance and improving velocity.
