This paper addresses the dam-break problem for particle suspensions, that is, the flow of a finite volume of suspension released suddenly down an inclined flume. We were concerned with concentrated suspensions made up of neutrally buoyant non-colloidal particles within a Newtonian fluid. Experiments were conducted over wide ranges of slope, concentration and mass. The major contributions of our...

The objective of this study is to improve Eulerian-Eulerian models of particle-laden turbulent flow. We begin by understanding the behavior of two existing models—one proposed by Simonin von Kármán Institute of Fluid Dynamics Lecture Series, 1996 , and the other by Ahmadi Int. J. Multiphase Flow 16, 323 1990 —in the limiting case of statistically homogeneous particle-laden turbulent flow. The d...
