摘要
根据燃气排导系统内两相流场的分布特点,利用可压缩雷诺N-S平均方程对流场进行计算。湍流模型采用标准k-ε二方程模型,采用颗粒轨道模型对颗粒相进行模拟,利用FLUENT就发射高度及燃烧室压强对三维流场参数分布的影响进行了重点分析,为优化发射结构设计提供了重要的理论依据。
According to the distribution characteristics of two-phase flow field in gas exhaust system,the flow field can be calculated by using compressible Reynolds-averaged Navier-Stokes equation.The turbulent model adopts the standard k-εtwo-equation model,and the particle phase is simulated by using particle trajectory model.Then the influence of launching height and pressure on the distribution of three-dimensional flow field parameters is analyzed by using FLU⁃ENT,which can provide an important theoretical basis for the optimization of launching structure design.
