Fluctuations of grains inside a discharging two-dimensional silo.
We present experimental data corresponding to a two-dimensional dense granular flow, namely, the gravity-driven discharge of grains from a small opening in a silo. We study the local velocity field at the scale of single grains at different places with the help of particle-tracking techniques. From these data, the velocity profiles can be obtained and the validity of some long-standing approach...
متن کاملGranular matter in a silo
A model for slow accumulation of granular matter in a silo is considered. For the case of a circular silo with central point source the prooles of the standing and rolling layers are explicitly computed. The computed shapes agree qualitatively with experimental observations and seem better justiied than results with constant speed of the rolling layer.
متن کاملBag Silo Densities and Losses
Bag silos made at three research farms in 2000 and 2001 were monitored at filling and emptying to determine densities and losses. A total of 47 bags (23 alfalfa, 1 red clover, 23 whole−plant corn) were made, and losses were calculated on 39 of the silos. Dry matter (DM) density ranged from 160 to 270 kg/m3. Dry matter density increased with DM content in hay crop silages on average 2.9 kg/m3−% ...
متن کاملMy world now. Life in a nursing home, from the inside.
This is my world now. It's all I have left. You see, I'm old. And I'm not as healthy as I used to be. I'm not necessarily happy with it but I accept it. Occasionally, a member of my family will stop in to see me. He or she will bring me some flowers or a little present, maybe a set of slippers I've got 8 pair. We'll visit for a while and then they will return to the outside world and I'll be al...
متن کاملForce probing of individual molecules inside the living cell is now a reality.
Biological systems can be quantitatively explored using single-molecule manipulation techniques such as optical or magnetic tweezers or atomic force microscopy. Though a plethora of discoveries have been accomplished using single-molecule manipulation techniques in vitro, such investigations constantly face the criticism that conditions are too far from being physiologically relevant. Technical...
