The behavior of flows containing dense particles is very complex. Due to the particle-particle collision effect and hydrodynamic effect caused by the fluid existing in-between particles, particles make spontaneous structures. Flow characteristics are heavily depending on these internal structures and it is important to know why and what sort of structure is formed in the flow field. In the present study, internal flow structures of the flow containing dense particles are calculated by coupling Full-resolved DNS and DEM (Discrete Element Method).
