| 摘 要： | 以雷诺实验为例，采用计算流体力学CFD软件进行模拟，建立了相应的物理和数学模型，得到了流体质点的流线。结果表明，速度在小于0．008m／s时，模拟结果显示流态为层流，速度大于0．015m／s时，流态为紊流。

| Abstract: | Taking Reynolds experiment as an example,simulation is accomplished with the computational fluid dynamics(CFD) software,corresponding physical and mathematical model are established and the streamline of fluid particle is got.The results show that,when velocity is less than 0.008m/s,flow condition is laminar flow and when velocity is more than 0.015m/s,flow condition is turbulent flow. |
