Operating charts for continuous sedimentation II: Step responses
(2005) In Journal of Engineering Mathematics 53(2). p.139-185- Abstract
- The process of continuous sedimentation of particles in a liquid has often been predicted by means of operating charts and mass-balance considerations, where the underlying constitutive assumption is the one by Kynch. Much more complex operating charts (concentration-flux diagrams) can be obtained from a one-dimensional model of an ideal continuous clarifier-thickener unit. The engineering concept of 'optimal operation' is defined generally as a special type of solution of the model equation, which is a conservation law with a source term and a space-discontinuous flux function. All qualitatively different step responses (with the unit initially in optimal operation in steady state) are presented and classified in terms of operating... (More)
