| 摘 要： | 本文研究了明渠中气液分层层流、分层紊流情况下的水流量增加或阻力减小规律。研究表明,明渠中的气液分层层流、分层紊流,即在近壁层内充以空气,可以在相同条件下明显地增大明渠的水流量,实现有效的减阻。

| Abstract: | In this paper the gas-liquid stratified laminar and turbulent flows in open channel and the laws for water flow rate increase and drag reduction have been studied. It is pointed out that the water flow rate can obviously be increased, i. e. the drag can be reduced in gas-liquid stratified laminar and turbulent flows. |

| Keywords: | open channel stratified flow aeration drag reduction. |
