A Mathematical model of clarifier thickener units
(2005)
We review a recent analysis of a clarifier-thickener model for flocculated suspensions. The resulting governing PDE is a strongly degenerate convection-diffusion equation with discontinuous flux. A new numerical example ...
Seismic reflectivity of a carbon dioxide flux
(Asociación Argentina de Mecánica Computacional, 2012-11)
In the context of the geological storage of carbon dioxide (CO2), thecharacterization of the injected CO2 in a reservoir is of primeimportance for volume capacity evaluation and long-term siteperformance. In this article, ...
A NUMERICAL DESCENT METHOD FOR AN INVERSE PROBLEM OF A SCALAR CONSERVATION LAW MODELLING SEDIMENTATION
(SPRINGER, 2008)
This contribution presents a numerical descent method for the identification of parameters in the flux function of a scalar nonlinear conservation law when the solution at a fixed time is known. This problem occurs in a ...
UNCERTAINTY QUANTIFICATION FOR A CLARIFIER-THICKENER MODEL WITH RANDOM FEED
(SPRINGER, 2011)
The continuous sedimentation process in a clarifier–thickener can be described by a scalar nonlinear conservation law for the solid volume fraction. The flux is discontinuous with respect to space due to the feed mechanism. ...
A NUMERICAL DESCENT METHOD FOR AN INVERSE PROBLEM OF A SCALAR CONSERVATION LAW MODELLING SEDIMENTATION
(SPRINGER, 2006)
This contribution presents a numerical descent method for the identification of parameters in the flux function of a scalar nonlinear conservation law when the solution at a fixed time is known. This problem occurs in a ...
Leyes de conservación con flujo discontinuo modelando columnas de flotación = Conservation laws with discontinuous flux modeling flotation columns.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas, 2022)
En esta tesis, se utiliza un modelo unidimensional dinámico desarrollado recientemente, formulado en términos de EDPs para predecir el proceso simultáneo de flotación de burbujas y
sedimentación de partículas que no están ...
A fully adaptive multiresolution scheme for shock computations
(Kluwer Academic/plenum Publ, 2001-01-01)
The scheme is based on Ami Harten's ideas (Harten, 1994), the main tools coming from wavelet theory, in the framework of multiresolution analysis for cell averages. But instead of evolving cell averages on the finest uniform ...
