An analysis of phase distribution and turbulence in dispersed particle/liquid flows

An analysis of dilute, turbulent particle/liquid two-phase flow is presente d. The three-dimensional conservation equations that govern turbulent motio n in solid/fluid hows are derived using ensemble averaging, and the unknown terms in these equations are constituted to achieve closure. These closure terms include the shear stress due to interparticle collisions, the corres ponding terms in the Reynolds stress equation, the force and dissipation du e to particle-wall collisions, and the interfacial work due to particle/tur bulent eddy interaction. The resultant two-fluid model was then evaluated u sing a computational fluid dynamic (CFD) solver and the predictions were co mpared with experimental data. Good agreement was observed for a variety of flow conditions.
