Unresolved CFD-DEM#

This section includes examples related to multiphase fluid-solid flows. We organize the examples from the single phase flow in porous media (packed bed example) to multiphase flows (solid-gas, solid-liquid fluidized beds, and pneumatic conveying). The packed bed example uses the lethe-fluid-vans solver which solves the Volume Average Navier Stokes (VANS) equations. The fluidized bed, the spouted bed, the Boycott effect, and the pneumatic conveying examples use the lethe-fluid-particles solver which solves the VANS equations for the fluid phase coupled with the DEM equations for the solid phase.
