摘要: Saltation threshold data from three wind tunnels and hydraulic flumes are presented to show that the dimensionless friction speed for small particles is a continuous function of particle-to-fluid-density ratio. In addition, grain-friction Reynolds number an interparticle force term. The variation with density ratio seems be due relative energy which impact other initiate saltation.
