Abstract

A cubic enclosure in which the particles are driven by a three-dimensional sinusoidal gravitational field is studied to search for the applicability limit of binary collision model in dense particle-laden flows. It is found that the minimum local void fraction of the particle-laden flow has to be over 0.6 to assure the particle overlapping extent being less than 5% with adopting the binary collision model in the simulation. In addition, the ratio of computational time step to the mean free time has to be less then 10 -4 to obtain invariant prediction of the particle overlapping extent.
