摘要
本文在实验和理论分析的基础上,得到了涡管排沙的计算公式,即耗水率W、开口宽度b及排沙率E的表达式。涡管排沙节约用水,用10％以下的耗水量,能排出80％的推移质来沙。
On the basis of theoretic analysis and flume experiments, the excluding expresions, including the expresions of extraction ratio, the width of the opening of vortex tube and excluding rate, have been obtained. If reasonably designed, a vortex tube sediment excluder can make use of water discharge less than ten percent of the total oncoming flow to exclude the sediment more than eighty percent of the total.
