摘要
An unknown in coupled Eulerian-Lagrangian models for particle flow,such as CFD-DEM,which has received fairly little attention in the literature to date is the size of the filter width in the transfer kernel.This work provides a preliminary glimpse at how this parameter can influence the solution in cold-flow,unbounded fluidization.Comparison to previously published direct numerical simulation data is used to suggest an appropriate range for this parameter.
