Determination of obstacles in Stokes flow by boundary measurement. Electronic Journal of Differential Equations, 2017(233), pp. 1-9.1072-6691https://hdl.handle.net/10877/16002We 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.Text9 pages1 file (.pdf)enAttribution 4.0 InternationalStokes flowReciprocity gap functionCalculus of variationsTopological sensitivityArticle
