One of the roll waves picked him up and threw him into the back of the truck.
The huge dark snout was moving nearly five hundred feet a minute and the rest of the flow behind was coming twice as fast, making roll waves as it piled forward against itself — this great slug, as geologists would describe it, this discrete slug, this heaving violence of wet cement.
Limited data exists in literature on roll waves.
The flow was set to generate roll waves and controlled disturbances were applied at the inlet to develop roll waves.
This paper presents a methodology for measuring a particular non-stationary phenomenon that occurs under specific conditions, namely, roll waves.
The capacity of the model to describe the full transition scenario as commonly seen in the formation of roll waves: from uniform flow to 1D roll waves, and, finally, to 2D transverse 'fingering' of the wave profiles, is shown.
The objective of this work is to contribute to this database and to describe a useful experimental method for measuring roll waves.
With the increase of liquid flow rate, the roll waves appear and the wave amplitudes are increased significantly, which may obviously enhance the performance in the LDD absorption and regeneration process due to the increased contact area.
The accuracy of such an approach is tested on 2D analytical solutions describing the flow with linear with respect to the space variables velocity, and on the solutions describing 1D roll waves.
Beach Estates, Santa Teresa Rolling waves set the soundtrack to this exclusive coastal haunt on the Nicoya Peninsula.
Rolling waves were already washing straight over the promenade wall in Battery Park, Manhattan, on Monday morning.
