What is CPFD?
Computational-Particle-Fluid-Dynamics = CPFD
- Particles are not a fluid
- That's what makes it different...and difficult
Particle Physics is Correct
- Discrete solid materials
- Size & density distributions with multiple species closepacking
Fluid can be Either a Gas or Liquid
- Compressible gas with Equation of State
Particle Motions are Solved with a Langrangian Approach
- Gridless formulation gives infinite spatial resolution
- Fully coupled to the fluid phase using complex spatial gradients
- Robust stress tensor for forces near closepacking
- Coefficient of friction - static + dynamic
Accurate and Fast "solver"
- Well validated
- Ti02 reactor simulated in 180 sec in 2 days
