A non-local theory is proposed to model dense granular flows. The idea is to describe the rearrangements occurring when a granular material is sheared as a self-activated process. A rearrangement at one position is triggered by the stress fluctuations induced by rearrangements elsewhere in the material. Within this framework, the constitutive law, which(More)

O’Brien U.S. Department of Energy National Energy Technology Laboratory (NETL) On a turbulence theory of multiphase flow Since the transient simulations of multiphase flow are very computationally intensive, there has been some effort to develop RANS-like turbulence theories for gas/particle flows, such as those in circulating fluidized(More)
