Turbulent Separating Flow over Humps in an Open Channel
- 234 Downloads
Two dimensional flow past various obstacles placed in a rectangular cross section flume was studied. Position and extent of separation and the distribution of turbulence produced in the shear zone were key elements of the study. Parameters varied were geometry of the obstacles (vertical wall, wave shaped sills), depth of flow and discharge. For comparison measurements were carried out in a density stratified flow with some of the obstacles.
