Description

The averaging model performs the Lagrangian->Eulerian mapping of data, especially it computes the average particle velocity on the Eulerian grid, usually referred to as $U_s$ .

The dense model is supposed to be applied to cases where the granular regime is rather dense and several particles per CFD cell may be encountered. The particle velocity inside a CFD cell is then evaluated as average velocity of all particles in a that cell.
