Effect Of Gap Flow On The Shallow Wake Of A Sharp-Edged Bluff Body – Turbulence Parameters, A.M Shinneeb, R. Balachandar
Effect Of Gap Flow On The Shallow Wake Of A Sharp-Edged Bluff Body – Turbulence Parameters, A.M Shinneeb, R. Balachandar
Civil and Environmental Engineering Publications
This experimental study was carried out to investigate the turbulent wake generated by a vertical sharp-edged flat plate suspended in a shallow channel flow with a gap near the bed. The objective of this study is to understand the effect of the gap flow on the turbulent wake by studying two different gap heights between the channel bed and the bottom edge of the bluff body. These two cases were compared to the no-gap case which is considered as a reference case. The maximum flow velocity was 0.45 m/s and the Reynolds number based on the water depthwas 45,000. Extensivemeasurements …

Mean Characteristics Of Fluid Structures In Shallow-Wake Flows, Ram Balachandar
Civil and Environmental Engineering Publications
An enhanced picture of the formation of fluid structures including the effect of the free surface and the bed is captured via a numerical solution of flow past a bed mounted bluffbody. A numerical comparison for the fluid structures observed in a time-averaged field of the shallow-wake flow behind a bluffbody utilizing the rigid-lid assumption and volume of fluid method is carried out in this study to bring forth the shortcomings in previous studies. The transient three-dimensional governing Navier–Stokes equations are computationally solved using a finite volume technique with Detached Eddy Simulation as a turbu- lence model. A flat wave …
