Mixing length computations for tracer flow in heterogeneous porous media by multiscale and lagrangian procedures

Next Thursday December 19th. Alexandre Santos Francisco will be talking at CCM – Chair of Computational Mathematics from the Universidade Federal Fluminense (Brazil) to talk about “Mixing length computations for tracer flow in heterogeneous porous media by multiscale and lagrangian procedures”.

Abstract. The mixing of the pure fluid and the tracer fluid is a consequence of flow velocity variability owing to permeability heterogeneities, and can be viewed as an effective dispersion process. The stochasticity of the velocity field is responsible by arising a macroscopic mixing region. The goal of this proposal is to investigate the mixing length growth in tracer flows that results from the permeability heterogeneities. We focus on single-phase, miscible flow in rigid porous media, which corresponds physically to a particular enhanced oil recovery. The heterogeneity occurring on the small length scales have to be incorporated stochastically, on the basis of random permeability fields. We intend to employ multiscale and lagrangian procedures in order to compute correctly the mixing length growth, with low computational cost and accurately.

The event is finished.
