A Stabilized Finite Volume Element Formulation for Sedimentation-Consolidation Processes
A model of sedimentation-consolidation processes in so-called clarifier-thickener units is given by a parabolic equation describing the evolution of the local solids concentration coupled with a version of the Stokes system for an incompressible fluid describing the motion of the mixture. In cylindrical coordinates, and if an axially symmetric solution is assumed, the original problem reduces t...
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...
متن کاملThixotropy of Blood and Proneness to Thrombus Formation
• "While the viscosity of blood lias been studied extensively (Copley, Stainsby, and Bayliss-), only a few studies have involved the use of a rotational viscometer. These included Brundage, Wells and Merril, and Wells et al.,-~ the latter applying a Brookfield cone plate viscometer. Neither study was carried out at rates of shear below 10 seer. The present author considered that the region belo...
متن کاملThixotropy: The Case of Mexico City Soils
Thixotropy implies non-equilibrium initial conditions after remolding. At the macroscale, thixotropy manifests as the regain in mechanical properties. At the microscale, thixotropy involves phenomena such as contact creep and interparticle force redistribution, homogenization of pore pressure (in saturated and partially saturated soils), altered ionic distribution and mobility, and the effects ...
متن کاملShear thinning and thixotropy of HMHEC and HEC water solutions
Steady state viscosity and thixotropy of hydrophobically modified hydroxyethyl cellulose ~HMHEC! and nonassociative cellulose water solutions are studied. Although all the samples are shear thinning, only the HMHEC is thixotropic, since the migration of hydrophobes to micelles is controlled by diffusion. The Cross model fits steady state curves. The Mewis model, a phenomenological model that pr...
