| 摘 要： | 用任意拉格朗日－欧拉（ＡＬＥ）法模拟了ＭＰＣ模块的二维定常可压缩湍流流场．以某一型号发动机的ＭＰＣ排气系统为例，对仅支管进气及支管总管都进气两种情况获得了速度场和压力场，揭示了ＭＰＣ模块三分支联接湍流流动特性，也为用ＡＬＥ法模拟ＭＰＣ模块三维流场奠定了基础．

| Abstract: | A two dimensional stationary compressible
turbulent flow field in MPC exhaust manifold junctions is numerically simulated using the ALE
method. With the MPC exhaust manifold junction of a given engine type as an example, the
velocity fields and the contours of static pressure showing the turbulent flow features have been
obtained for the case when gas enters only at the entrance of the ejecting nozzle or when gas
enters simultaneously at the entrance of the ejecting nozzle and the main pipe. |
