Large and very large scale motions in roughbed open-channel flow
Long duration PIV measurements in rough-bed (glass beads) open-channel flow (OCF) reveal that the pre-multiplied spectra of the streamwise velocity has a bimodal distribution due to the presence of large and very large scale motions (LSMs and VLSMs ...

Experimental and Theoretical Investigation of Moisture Dynamics in Intermittent Drying of Rough Rice
Intermittent drying is a satisfactory technique for drying of heat sensitive grains especially rough rice. This method consists of two separate stages applied intermittently: drying and tempering.

Effects of Regularly Arrayed Roughness on Flow Resistance and Turbulent Flow Structure in an Open Channel [PDF]
Effects of regularly arrayed cylindrical and sphere roughness on flow resistance and turbulent characteristics in an open channel have been investigated over a completely rough-bed with uniform stainless steel rods and glass beads.

Measurement of turbulent flow in a narrow open channel
The paper presents the experimental results of turbulent flow over hydraulically smooth and rough beds. Experiments were conducted in a rectangular flume under the aspect ratio b/h = 2 (b = width of the channel 0.5 m, and h = flow depth 0.25 m) for both ...

The Effect of Air on Granular Size Separation in a Vibrated Granular Bed
Using high-speed video and magnetic resonance imaging (MRI) we study the motion of a large sphere in a vertically vibrated bed of smaller grains. As previously reported we find a non-monotonic density dependence of the rise and sink time of the large ...

Turbulent Characteristics of Shallow Flow Over Rough Surface with Regularly Arrayed Spheres [PDF]
Turbulent nature of near-bed flow field was investigated in an open channel over a rough-bed artificially arrayed with glass beads, where ratios of the glass diameter to flow depth are 0.3, 0.5 and 0.8.

Direct numerical simulation of open-channel flow over a fully-rough wall at moderate relative submergence [PDF]
Direct numerical simulation of open-channel flow over a bed of spheres arranged in a regular pattern has been carried out at bulk Reynolds number and roughness Reynolds number (based on sphere diameter) of approximately 6900 and 120, respectively, for ...
