Particle Tracing Module, General Introduction, V4.3b
Model ID: 12009
The Particle Tracing Module extends the functionality of the COMSOL Multiphysics environment for computing the trajectory of particles in a fluid or electromagnetic field, including particle-field interactions. Any add-on module combines seamlessly with the Particle Tracing Module and gives you access to additional modeling tools and fields to drive the particle motion.
Applications include: flow visualization, mixing, spraying, particle separation, mass spectrometry, ion optics, beam physics, ion energy distribution functions, and acoustic streaming.
A variety of different forces are allowed to act on the particles such as those of charged particles in electric or magnetic fields, drag forces in CFD, electrophoretic, acoustic streaming, as well as user-defined forces. Loss or gain of mass, charge, or similar quantities may be represented as auxiliary variables and equations for each particle along its trajectory. Particles can be massless or have mass, where the movement is governed by Newtonian, Lagrangian, or Hamiltonian formulations from classical-mechanics. Low-level access to the mathematical formalism is available for customized simulations.
