Original · EN
A new model for the drag coefficient of a sphere in a concentrated system is described. It is based upon a cell-averaged model for the Stokes regime combined with a physically motivated extrapolation to arbitrary Reynolds number. It can be used as an alternative to the isolated particle drag coefficient in Euler-Lagrange modelling of solid-liquid multi-phase flow.The corresponding drag force also provides a dynamic bed equation for use in Euler-Euler modelling.
