Feedback Instability in a Boundary-layer Flow over Roughness
Linear stability of an incompressible triple-deck flow over a wall roughness is considered for disturbances of high frequency. The wall roughness consists of two relatively short obstacles placed far apart on an otherwise flat surface. It is shown that the flow is unstable to feedback or global mode disturbances. The feedback loop is formed by algebraically decaying disturbances propagating ups...
متن کاملEffect of Crest Roughness on Flow Characteristics over Circular Weirs
Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures. In the present research, numerous experiments under different hydraulic conditions were performed on a physical model to study the effects of roughness on flow hydraulics over a circular weir. The flow hydraulics incl...
متن کاملTurbulent flow over a long flat plate with uniform roughness
For turbulent boundary-layer flow under a uniform freestream speed U∞ over a plate of length L, covered with uniform roughness of nominal sand-grain scale ks , the physical behaviors underlying two distinguished limits at large ReL ≡ U∞L/ν are explored: the fully rough wall flow where ks/L is fixed and the long-plate limit where Rek ≡ U∞ks/ν is fixed. For the fully rough limit it is shown that ...

متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
