PASSAGE Discrete Element Method (DEM) Software is for
predicting the flow particles under a wide variety of forces. It can
be used alone or together with our
of Passage Discrete Element Method Software:
- Equations of motion are
solved for translation and rotation of individual particles
traveling in electrostatic, magnetic, or gravitational fields.
- The size of the particles
can be in the order of microns or larger. All appropriate
forces are included in the formulation.
- The particles can be of
different shape and size with a given distributions.
- The particles can carry
charge. Individual charging of particles are calculated.
- Different properties of the
particles such as charge, temperature, etc. can be predicted by
tracking the motion of each particle.
- Different types of boundary
surfaces can be modeled whether they are stationary or moving.
- A user-friendly pre- and
post-processor is provided to input the geometry of the
boundaries and the particles, as well as the display of motion
and other properties of the particles.
- Structural deformations of
rollers, belts driving the particles are also included in the
- Runs on PC-based
Some Application Areas
- Computers Printers
- Food processing
- Material processing
- Mixing problems
- Minimize the cost and time
of traditional prototype building and testing, thus shortening
product design cycles
- Designs can be analyzed and
modified on the computer before expensive and time consuming
design decisions are finalized.
Advantages of Passage DEM+FLOW
By coupling PASSAGE: Discrete Element Modeling (DEM) and 3D FLOW
software a variety of problems can be solved which can not be
treated by using either one model individually. This capability
allows modeling of liquids, gases, solid particles and their
mixtures for many industrial problems in both micro and macro
scales. It can be applied to process modeling of mixing, wetting,
coating, filtration, fermentation and filling operations for
applications in food, pharmaceutical, chemical, metals, plastics,
glass, ceramics, powders processing and emission control.
DEM and FLOW modules can be coupled
in a variety of ways depending
on the application.
