[Description:]
|
|
|
|
The force model performs the calculation of forces (e.g. fluid-particle
|
|
interaction forces) acting on each DEM particle. The {MeiLift} model calculates
|
|
the lift force for each particle based on Loth and Dorgan (2009). In case the
|
|
keyword "useSecondOrderTerms" is not specified, this lift force model uses the
|
|
expression of McLaughlin (1991, J. Fluid Mech. 224:261-274).
