A 2-D asymmetric exclusion model for granular flows
A 2-D version of the asymmetric exclusion model for granular sheared flows is presented. The velocity profile exhibits two qualitatively different behaviors, dependent on control parameters. For low friction, the velocity profile follows an exponential decay while for large friction the profile is more accurately represented by a Gaussian law. The phase transition occurring between these two be...
متن کاملAsymmetric exclusion model with impurities.
An integrable asymmetric exclusion process with impurities is formulated. The model displays the full spectrum of the stochastic asymmetric XXZ chain plus new levels. We derive the Bethe equations and calculate the spectral gap for the totally asymmetric diffusion at half filling. While the standard asymmetric exclusion process without impurities belongs to the KPZ universality class with an ex...
متن کاملA predictive, size-dependent continuum model for dense granular flows.
Dense granular materials display a complicated set of flow properties, which differentiate them from ordinary fluids. Despite their ubiquity, no model has been developed that captures or predicts the complexities of granular flow, posing an obstacle in industrial and geophysical applications. Here we propose a 3D constitutive model for well-developed, dense granular flows aimed at filling this ...
متن کاملA Model for Granular Flows over an Erodible Surface
We present a framework for modeling a dry geophysical mass of granular material – a debris or volcanic avalanche or landslide – flowing over an erodible surface. We also describe a computing environment that incorporates topographical data into a parallel, adaptive mesh computational algorithm that solves the model equations.
متن کاملAsymmetric simple exclusion model with local inhomogeneity
We study a totally asymmetric simple exclusion model with open boundary conditions and a local inhomogeneity in the bulk. It consists of a one-dimensional lattice with particles hopping stochastically with equal rates to the right at all lattice sites except one where the jump rate is different. Approximate stationary-state solutions and phase diagrams are obtained and compared with Monte Carlo...
