Abstract:
We study the determination of some obstacles in a Stokes flow domain
with overdetermined boundary data. We use a method based on the topological
sensitivity technique associated to the reciprocity gap function concept.
We develop an asymptotic formula between the flow parameters and the
boundary data. The obtained formula is interesting and serve as a useful
tool to develop an accurate and robust numerical method in geometry
inverse problems.
