摘要
根据波浪作用下泥沙颗粒的受力情况,探讨了在紊动流体中作用在泥沙颗粒上的体积力比在恒定流中作用在泥沙颗粒上的体积力小的原因,阐述了谢尔德准数既适用于紊流状态,也适用于恒定流状态。
The force acting on sediment particle was analyzed in the paper. The reason why the volume force acting on sediment particle in a steady flow is more than that in a turbulent flow was also inquired in it. It was described that the Shelder's Number is suitable for not only turbulent flow, but also steady flow.
