報告題目A non-iterative method for recovering an inclusion in an unbounded Stokes-Brinkman flow.

報告內(nèi)容 In this talk, we focus on the inverse problem of recovering an inclusion immersed in the unbounded viscous flow which is governed by the Stokes-Brinkman equations. The well-posedness of the model problem is first proved by employing the boundary integral equation method. Then a novel issue of the linear sampling method (LSM) and factorization method (FM) are proposed for reconstructing the shape and location of the inclusion only from the exterior velocity measurements, yielding a fast imaging algorithm. Numerical examples are presented to demonstrate the feasibility and effectiveness of the reduced inversion algorithm.
