Bubbling Bed

  • 500 micron sand uniformly fluidized using air at 1 m/s
  • Using 8000 parcels with 668 particles/parcel
  • DEM tracks all particles-particle and particle-wall collisions

Cartesian Grid – 2D Hourglass


2D Gas/Solids flow in an hourglass, colored by volume fraction, to illustrate sand flowing in the hourglass. Left: No slip boundary condition. Right: Free slip boundary condition.

Cartesian Grid – Hairpin Vortices


3D single phase flow over a hemisphere. Isosurfaces of lambda_2 eigenvalues are shown, colored by velocity magnitude, to illustate the formation of hairpin Vortices over a Hemispheric protuberance.

Cartesian Grid – MFiX Logo


MFIX logo placed in a bubbling bed, colored by volume fraction. Illustrates the capability to represent complex geometry.

Cartesian Grid – Spouted Bed


2D spouted bed simulation, colored by volume fraction.
