扩张角对隔离段抗反压能力影响的数值模拟研究

Research of imilative the offect of isolator divergent angle on flow fielas

这里利用计算流体力学软件Fluent,采用K-ε湍流模型,近壁面采用非平衡壁面函数方法处理,控制方程的离散采用二阶迎风格式,对隔离段的流场进行了数值模拟,并分析了扩张角对隔离段抗反压能力的影响。

In this paper, the flow fields within scramjet engine isolator has been simulated using the Fluent CFD code. The current version of this code employs turbulence model, second order upwind interpolation scheme, coupled implicit method. The effect of isolator divergent angle on flow fields are also analyzed and discussed.
