WebThis flow separation creates a zone of reverse circulation downstream of the obstacle. The zone of reverse circulation is an area of turbulence and backflow. The point of flow reattachment is where most erosion occurs … WebSubcritical flow in a short expansion tends to become detached from its sidewalls and create turbulent eddies. This phenomenon can cause undesirable losses of flow energy and channel erosion. This paper numerically investigates the effects of a triangular hump fitted at the bottom of the expansion on flow separation reduction. The results are validated …

WebIn this paper, the transient flow simulation in an annular isolator under rotating feedback pressure perturbations simplified from the rotating denotation wave (RDW) is performed. The instantaneous flow characteristics and the self-similarity of the isolator flow-field are investigated in detail.

"In fluid dynamics, flow separation or boundary layer separation is the detachment of a boundary layer from a surface into a wake. A boundary layer exists whenever there is relative movement between a fluid and a solid surface with viscous forces present in the layer of fluid close to the surface. The flow can be … See more The flow reversal is primarily caused by adverse pressure gradient imposed on the boundary layer by the outer potential flow. The streamwise momentum equation inside the boundary layer is approximately stated as See more The tendency of a boundary layer to separate primarily depends on the distribution of the adverse or negative edge velocity gradient See more When the boundary layer separates, its remnants form a shear layer and the presence of a separated flow region between the shear layer and surface modifies the outside See more 1. ^ White (2010), "Fluid Mechanics", Section 7.1 (7th edition) 2. ^ Anderson, John D.
