Collision Modeling
Collision modeling is the only part in this particulate flow DNS work since there is no way to resolve the scales when collision happens.
Lots of work are done in this area. As a simpler investigation approach, a granular dynamics simulation code is developed to test the collision models to first make sure the collision model works even without the fluid flow influence.
- Event driven hard sphere collision: instantaneous collision and no overlap allowed.
