Date of Defense 2009-05-20 Availability unrestricted Abstract This thesis presents and evaluates methods for solving the 1D viscous Burgers’ partial differential equation with finite difference, finite element, and proper orthogonal decomposition (POD) methods in the context of an optimal control inverse problem. Based ondownstream observations, the initial conditions that optimize a lack-of-fit cost functional are
reconstructed for a variety of different Reynolds numbers. For moderate Reynolds numbers, our POD method proves to be not only fast and accurate, it also demonstrates a regularizing effect on the inverse problem.
