The ability to create logical groups of highly granular flow
information simplifies troubleshooting, speeds up the planning process and provides simple yet flexible monitoring options for users.
Florida Keys Mosquito Control District would like to purchase 3 Granular Flow
Controller Units (GFC), one for each of the Districts helicopters, which will allow the aircraft to be flown at variable speeds and still maintain accurate application rates.
Gidaspow, "Bubbling fluidization model using kinetic theory of granular flow
," AIChE Journal, vol.
The program is built on a depth-averaged model for an incompressible Coulomb continuum, a "shallow water" granular flow
, based on the work of Savage & Hutter (1989), Iverson (1997), Iverson & Denlinger (2001), Denlinger & Iverson (2001) and Mangeney-Castelnau et al.
A precise model, for granular flow
would be particularly useful, in optimizing processes such as pharmaceutical, manufacturing and grain production, where tiny pills and grains pour through industrial chutes and silos in mass quantities, said Ken Kamrin, professor in the Massachusetts Institute of Technology's department of mechanical engineering.
The Discrete Element Modeling (DEM) can be used to simulate the motion of the granular flow
of sand, food particles, metal powders, plant matter, capsules and slurries, etc.
Among the topics are a hyperbolic model of granular flow
, symmetric solutions to multi-dimensional conservation laws, asymptotic analysis in the thermodynamics of viscous fluids, instability in solitary waves for a nonlinearly dispersive equation, a local and low-order Navier-Stokes-Korteweg system, and finite difference methods for discretizing singular source terms in a Poisson interface problem.
The limited knowledge regarding granular flow
is considered problematic by engineers and scientists due to the extensive presence of these systems in modern processes.
c], of a granular flow
system due to the motion of charge-carrying particles can be calculated by the following equation:
Further studies of these features may shed light on the nature of granular flow
and aid in the development of improved methods of mixing, sorting, and handling granular materials.
Physicists demonstrate the effect of enclosures on granular flow
by using an hourglass with slightly different funnel angles.
This behavior will be particularly important for asteroids that are rubble-piles, as spacecraft trying to land or drill into these could easily destabilize regolith, causing granular flow
