摘要:
The purpose of this paper is to show how small, submerged vortex generators can be used for adjusting the flow pattern in open-channel flows. The vortex generators are vanes or foils installed on the channel bottom in certain configurations. Their height is typically 0.2 to 0.5 times flow depth, their length is about 2 to 3 times their height, and their angle with the flow between 15° and 30°. Described are the adjustments of the flow field effected by a single vane, a vane pair, and several vanes arranged in arrays along one side of the channel. Experimental data are used to develop formulas for calculating the flow adjustments across a channel having vane arrays along one side.
