Models for Boundary Layer Separation: The Prandtl Equation and Beyond?

Speaker: Anne-Laure Dalibard, UPMC Paris 6

Location: Warren Weaver Hall 1302

Date: Thursday, April 13, 2017, 11 a.m.

Synopsis:

In this talk, I will present recent results for fluid boundary layers. The largest part of the talk will be devoted to a work in collaboration with Nader Masmoudi, in which we prove separation for the stationary Prandtl equation and justify Goldstein's singularity. I will then present some instability results for alternative boundary layer models: Prandtl equation with prescribed displacement thickness and interactive boundary layer models. This is an ongoing work with Helge Dietert, David Gérard-Varet and Frédéric Marbach.
