Fluid/Solid Flows 

title Left  Two Scales Simulations : Micro-Scale and Meso-Scale

 

 

 

DLM/FD simulation:

Grids size = dp/24 -> nb of cells ≈ 48×10^6    

Parallel simulation time on 128 cores ≈25 days

DEM/CFD simulation:

Grids size  ≈ 1.7d_p  -> nb of cells =756

Simulation time on 1 core ≈2 hours
