A Strongly Degenerate Convection-Diffusion Problem Modeling Centrifugation of Flocculated Suspensions

Raimund Bürger and Kenneth Hvistendahl Karlsen

Abstract: We prove existence and uniqueness of $BV$ entropy solutions of a strongly\linebreak degenerate convection-diffusion problem modeling centrifugation of flocculated suspensions. A modification of the generalized upwind method is employed to solve the initial-boundary value problem numerically, i.e., to simulate the centrifugation process.
