Shape Reconstruction for Unsteady Advection-Diffusion Problems by Domain Derivative Method

الملخص EN

This paper is concerned with the numerical simulation for shape reconstruction of the unsteady advection-diffusion problems.

The continuous dependence of the solution on variations of the boundary is established, and the explicit representation of domain derivative of corresponding equations is derived.

This allows the investigation of iterative method for the ill-posed problem.

By the parametric method, a regularized Gauss-Newton scheme is employed to theshape inverse problem.

Numerical examples indicate that the proposed algorithm is feasible and effective for the practical purpose.
