摘要:
A scaled-up Reynolds model of a sediment particle on a streambed has been used to study the drag force exerted by streamflow. The results have been presented as a data trend relating particle drag coefficient to particle Reynolds number. The modified drag coefficient and Reynolds number used take into account the presence of bounded shear flow by using a characteristic velocity determined from the relation between the approach flow velocity and the shear velocity on the streambed.
