Analysis of Velocity Lag in Sediment-laden Open Channel Flows
Laboratory experiments have recently confirmed that the streamwise particle velocity is largely less than that of the fluid in sediment-laden flows. This velocity lag is investigated analytically in the present study based on the drag force exerting on a particle in the presence of other neighbors. The normalized drag force or the hindrance coefficient is found generally dependent on the partic...
متن کاملTurbulent Shear Stress in Heterogeneous Sediment-laden Flows
Current knowledge of the mechanics of alluvial channels depends very largely on calculations of turbulent shear stresses; typical examples are the beginning of motion of sediment particles and sediment transport in alluvial channels. If shear stress can be well defined in clear-water flows, comparatively little is known about shear stresses in sediment-laden flows. Einstein and Chien (1955) pro...
متن کاملSluicing Flumes for Gauging Sediment-Laden Rivers
The sluicing flume that was designed is less capable of silting up and losing its calibration than its counterparts of standard sharp-crested compound weir design. The laboratory work described here led to a refinement in the design in the form of a short flume set into the lowest section of a compound Crump weir gauging installation. Critical flow occurs near the exit of this flume, and it is ...
متن کاملDynamic Spatially Augmented 3D Painting
We present techniques for creating a Spatially Augmented Reality for moving polygonal objects in an indoor environment, and a system that uses these techniques for painting in 3D on these objects in real time. By tracking the object and projecting on its different surfaces with two or more projectors, our system creates a dynamic spatially augmented version of the object that is registered with...
متن کاملGranular and Particle-Laden Flows
This research programme at the Newton Institute was devoted to improving the understanding and mathematical modelling of granular and particle-laden fluid systems as they arise in nature, in the laboratory and in industry. Geophysical examples of granular and particle-laden flows include rock avalanches, debris flows, mud flows and turbulent boundary layers with suspended particles, such as vol...
