| 摘 要： | 基于轴对称非定常可压缩N-S方程和VOF两相流模型,对水下固体发动机尾流场进行了数值仿真。结果较好地预示了尾流场燃气泡生长过程,得到了水下发动机工作初期尾流场形态及其演化过程。对发动机在水下和地面两种工况下的性能进行了对比。

| Abstract: | Based on axisymmetric unsteady-compressible N-S equations and VOF multiphase model,underwater solid motor tail flow was numerically simulated.Results show that well it has been well predicted for the growth process of the gas bubble in tail flow,as well as the shape and evolution process for tail flow.Then,work performance has been compared between motor working on the ground and working underwater. |
