SEMINAR: “Multiscale model reduction for flows in heterogeneous porous media”
|“Multiscale model reduction for flows in heterogeneous porous media”
We combine discrete empirical interpolation techniques, global mode decomposition methods, and local multiscale methods, to reduce the computational complexity associated with nonlinear flows in highly heterogeneous porous media. The resulting reduced-order approach enables a significant reduction in the flow problem size while accurately capturing the behaviour of fully-resolved solutions. Below we use of random boundary conditions in constructing snapshot vectors to build local basis functions. We show that by using only a few of these randomly generated snapshots, we can adequately approximate dominant modes of the solution space.
