Title: Experiment of ramp-type aerator shape on the impact of aeration under low Froude number
Abstract: By varying height and slope,different shape of ramp-type aerator models in variable slope flume are set to discover laws of cavity length and backwater depth over the aerator under different discharge.After analyzing the results of this experiment,the following conclusions are obtained: In the case of other conditions remain unchanged,flow discharge is proportional to the cavity length,and aerator height affects cavity length larger than aerator slope;greater the flow discharge is,lower backwater depth is.And the backwater depth increases with aerator height,indicating that aerator height is not proportional to the reduction of backwater depth;in this experimental condition,when the jet impact angle is 5.5°,the cavity backwater has emerged.Clearly,the emergence of cavity backwater is closely related with the jet impact angle,but in the final analysis it is relevant to flow conditions,the slope of flume,and the shape of aerator.
