| 摘 要： | 应用有限体积法对埋入式弯曲进气道内外流场进行了数值计算。用ＴＴＭ法生成贴体网格；用ｋ－ε模型模拟复杂湍流流动。计算结果表明，前方气流一部分被吸入管道，另一部分沿机体表面流向下游。管道入口背风侧存在一个分离区，管道内部气流畸变严重。计算结果和实验数据吻合较好。

| Abstract: | An investigation is given of two dimensional separated flow in and around a submerged curved inlet. The elliptic Navier Stokes equations,discretized by the finite control volume method are used in a body fitted curvilinear coordinate system.The results show that the flow in the duct is distorted and flow separation occurs behind the entry. Studies indicate that the computational results are in agreement with the experimental data,which will provide the basis for further simulation for three dimensional separated flows. |
