| 摘 要： | 应用计算流体力学技术,采用层流模型和湍流模型对净流量为0、一定雷诺数区间振荡流混合器单腔室中的层流流场和湍流流场进行了数值模拟计算。首次实现了振荡流混合器流场湍流流动阶段的三维数值模拟,较好地反映了湍流阶段振荡流混合器速度场分布状况,并获得了反映振荡流混合器速度场在一定雷诺数条件下非对称分布的模拟结果。

| Abstract: | Computational fluid dynamics(CFD) numerical simulation technique was used to simulate the flow field with both laminar model and turbulence model within a certain region of Reynolds number.The simulation was carried out on only one cell of oscillatory flow mixer(OFM)without net flow.The numerical simulation of 3-D turbulence flow in an OFM was firstly implemented.The phenomenon of asymmetric velocity field in an OFM was described successfully with simulation results. |

| Keywords: | mixer turbulent flow velocity fields numerical simulation |
