摘　　要：提出了研究圆管中分层流动的新模型 ,并利用该模型研究了非牛顿流体在圆管中层流 -紊流分层流动 ,得出了速度场的解析分布式。最后 ,研究了分层流动的阻力规律 ,为分层掺气减阻提供了理论依据。研究表明 。This paper proposes a new model to study stratified flow in pipe, and by using this model the laminar-turbulent stratified flow of non-Newtonian fluids in pipe is studied. Analytical correlations of velocity have been obtained. At last, the laws of flow resistance for stratified flow are researched, which provides a theoretical base for drag reduction by aeration in stratified flow. This research shows that aeration in stratified flow can make the drag reduce effectively.
