Free boundaries and boundary layers (Fall 2011)
ADVANCED TOPICS IN ANALYSIS (Free Boundries and Boundary Layers)
3 points. Fall term.
Monday, 9:30-11:20, N. Masmoudi.
Sorry for the late notice. There is no class on Monday
Prerequisite: some background in PDE.
The goal of the course is to study the inviscid limit of the free-boundary Navier-Stokes system and recover at the limit the free-boundary Euler system. This will allow us to link together two important problems in Ffuid Mmchanics, namely free boundary problems and boundary layers.
Grading: this course will be graded as a seminar course.
The first class will be on Monday September 12th.
The plan is to cover the following 3 parts :
I) Boundary layers
II) Free boundary problems
III) Inviscid limit of the free boundary Navier-Stokes sytem
For the first part :
1/ Derivation of some boundary layers systems :
Prandtl boundary layers,
Knudsen boundary layers
Boundary layers in homogenization, ...
2/ Existence resutls for some boundary layers systems
3/ Convergence resutls
