Methods for 3D computation of fluid-object interactions in spatially periodic flows

摘要

ew present computational methods for 3D simulation of fluid-object interactions in spatially periodic flows. These methods include a stabilized space-time finite element formulation for incompressible flows with spatial periodicity, automatic mesh generation and update techniques for fluid-object mixtures with spatial periodicity, and parallel implementations. The methods can be applied to uni- periodic (i.e., periodic in one direction), bi-periodic, or tri-periodic flows.
