A multiphase first order model for non-equilibrium sand erosion, transport and sedimentation
Three phenomena are involved in sand movement: erosion, wind transport, and sedimentation. This paper presents a comprehensive easy-to-use multiphase model that include all three aspects with a particular attention to situations in which erosion due to wind shear and sedimentation due to gravity are not in equilibrium. The interest is related to the fact that these are the situations leading to...
متن کاملNon-equilibrium pattern selection in particle sedimentation
In this paper, we explain some well known experimental observations in fluid solid interaction from a thermodynamic perspective. In particular we use the extremum of the rate of entropy production to establish the stability of specific patterns observed in single and multiparticle sedimentation in an infinite fluid and the sedimentation of spheres in the presence of walls. While these phenomena...
متن کاملGeneralized maps for erosion and sedimentation simulation
We propose a new approach, based on dynamic animation, to simulate geomorphological events such as erosion, sediment transportation and deposition. It relies on a generalized map representation of different geological layers. The topological evolution of these layers is driven by a set of displacements applied onto the vertices. The topological consistency of the model is guaranteed by a collis...
متن کاملMultiphase transport model for relativistic nuclear collisions
To study heavy ion collisions at energies available from the Relativistic Heavy Ion Collider ~RHIC!, we have developed a multiphase transport model that includes both initial partonic and final hadronic interactions. Specifically, the Zhang’s parton cascade ~ZPC! model, which uses as input the parton distribution from the heavy ion jet interaction generator ~HIJING! model, is extended to includ...
متن کاملAnalytical ultracentrifugation: sedimentation velocity and sedimentation equilibrium.
Analytical ultracentrifugation (AUC) is a versatile and powerful method for the quantitative analysis of macromolecules in solution. AUC has broad applications for the study of biomacromolecules in a wide range of solvents and over a wide range of solute concentrations. Three optical systems are available for the analytical ultracentrifuge (absorbance, interference, and fluorescence) that permi...
