OpenPDAC is an OpenFOAM module based on the module multiphaseEuler, distributed with OpenFOAM.
With respect to the origianl module, in OpenPDAC the equations from the kinetic theory for granualar flows are modified to model multiple dispersed solid phases.
In addition, a lagrangian library is included in the model (one-way coupling with the gas-solid mixture).
The module also implement an initialization of the hydrostatic pressure profile, which is needed for simulations on large domains. This allows you to use boundary conditions which are appropriate for inflow/outflow.
Six test cases are provided:
- a 3D explosion simulation with a synthetic topography;
- a 2D explosion simulation on a flat topography;
- an axisymmetric explosion simulation on a flat topography;
- a 2D dilute flow over a wavy surface;
- a 2D fluidezed bed with two solid phases;
- a 2D impinging flow with two solid phases.
