On the detection of immersed obstacles by
boundary measurements
This talk is devoted to the inverse problem of
determining the shape and location of a body immersed in a fluid, based on measured quantities
on the exterior boundary of the fluid domain. For certain fluid models, we
suggest an inverse algorithm that combines Newton method and the method of fundamental
solutions for the associated direct problems. Some numerical simulations are
presented to illustrate the feasibility of this approach in the two-dimensional case.
This is joint work with Nuno Martins (Faculdade de
Ciências e Tecnologia, Lisbon).
