[Description:]
|
|
|
|
The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The GidaspowDrag model is a model that calculates the particle based drag force following the correlation of Gidaspow which is a combination of Ergun (1952) and Wen & Yu (1966) (see Zhu et al. (2007): "Discrete particle simulation of particulate systems: Theoretical developments", ChemEngScience).
