Title:Examples of boundary layers in fluid mechanics
Seminar:Computational and Applied Mathematics Colloquium
Speaker:Anne-Laure Dalibard, Ecole Normale Superieure de Paris
Abstract Link:http://www.math.ens.fr/~dalibard
Abstract:
Boundary layer phenomena occur in various physical contexts (e.g. fluid dynamics, thermodynamics). A boundary layer might appear whenever a problem is described by a singular perturbation operator in a bounded domain. If the profile dictated by the singular operator does not match the conditions on the boundary of the domain, then the solution must be corrected in the vicinity of the boundary. In this talk, I will explain a method which allows to construct boundary layers in a systematic way, under some assumptions on the singular operator. I will also present some examples which do not fit into this framework, and for which some kind of "degeneracy" occurs.
