On a Quasilinear Coagulation-fragmentation Model with Diiusion

نویسنده

  • Herbert Amann
چکیده

We consider a system of a very large number of particles of very diierent sizes, suspended in a carrier uid. These particles move due to diiusion and superimposed transport processes, merge to form larger clusters, or fragment into smaller ones. In the present paper a mathematical model for such processes is derived, consisting of an innnite quasilinear reaction-diiusion system, coupled to the Navier Stokes equations for the motion of the suspension. We prove the well-posedness of this problem, derive a positivity result, and show that the total mass of the suspended particles is conserved.

Coagulation-fragmentation Processes

We study the well-posedness of coagulation-fragmentation models with diiusion for large systems of particles. The continuous and the discrete case are considered simultaneously. In the discrete situation we are concerned with a countable system of coupled reaction-diiusion equations, whereas the continuous case amounts to an uncountable system of such equations. These problems can be handled by...

An Asymptotic and Numerical Description ofSelf - Similar Blow - up in

We study the blow-up behaviour of two reaction-diiusion problems with a quasilinear degenerate diiusion and a superlinear reaction. We show that in each case the blow-up is self-similar, in contrast to the linear diiusion limit of each in which the diiusion is only approximately self-similar. We then investigate the limit of the self-similar behaviour and describe the transition from a stable m...

Center Manifolds for Quasilinear Reaction-diiusion Systems

We consider strongly coupled quasilinear reaction-diiusion systems subject to nonlinear boundary conditions. Our aim is to develop a geometric theory for this type of equations. Such a theory is necessary in order to describe the dynamical behavior of solutions. In our main result we establish the existence and attractivity of center manifolds under suitable technical assumptions. The technical...

Global Existence, Uniqueness, and Continuous Dependence for a Reaction-diffusion Equation with Memory

Global existence, uniqueness and continuous dependence on initial data are established for a quasilinear functional reaction-diiusion equation which arises from a two-dimensional energy balance climate model. Our approach relies heavily on the so-called stability estimates for linear evolution equations of parabolic type (cf. 6]).
