| Abstract: | 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. |
| Keywords: | non-Newtonian fluid pipe stratified flow turbulent flow new model drag reduction |
