| 摘 要： | 本文应用有限体积法以二个埋入式弯曲进气管道内外流场进行了数值分析计算，其中用ＴＴＭ法生成了较为合理贴体曲线坐标网格，用ｋ－ε双方程形式湍流模型近似地模化了进气道内外的复杂湍流流声援笔有关实验数据对照后表明：来自进气道前方的进气气流一部分被管道吸入，另一部分沿着机体表面方向流过，管道进气口背风侧处存在一个明显分离区，进气道内部气流流动已经出现了严重畸变，数值计算和有关实验数据吻合得较好，为进一步研究

| Abstract: | This paper presents investigation of two dimensional separated flow in and around a submerged curved intake by experiment and computation. The NavierStokes equations are employed which are discreted in body-fitted coordinate system by finite control volume method. The results show that the flow separation near and behind the inlet exists and the duct flow is distorted.Comparison between the calculation and experimental data is fairly satisfactory. |
