Sedimentation of spherical particles. †

  • Yellow and Red particles are identical. Different colors are used just for visualization purpose.
  • Simulation parameters
    • CFD Lattice: 256 x 256 x 512 mesh
    • Number of Particles: N = 100,000
    • Diameter of Particles: D = 4 mesh
    • Volume Fraction: Φ = 0.099
    • Particles Reynolds No.: Re ~ 0.1
    • Number of Iteration Steps: 32,400
    • Computation Time: 6 Days on Intel Core-i7-3.2GHz (with ICC+MKL+OMP)

  • Visualization
    • You can make the same animation as above with fileparticleshow_gravity.py to be loaded from GOURMET. Open "output.udf"
    • Instead, you can make a similar animation with fileparticleshow.py to be loaded from AVS/Express.
