On the Caracteristics of Vortices generating on a River Bed.
抄録
The vortices generating on a river bed were observed with 3 electro-magnetic flowmeters. Using obtained digital data, the distributions of velocity components, Reynolds stress, and energy spectrum were calculated. Distributions of diameter and velocity are represented in this paper. A conceputual model of river turbulence is proposed on the base of the results. Generating mechanism of horse-shoe vortices, sweeps, ejections, and boiles are explained based on the model.
