Turbulent Mixing and Solid Impact: Studies in Multiscale Modeling

Abstract

The principal directions of the research reported were fluid interface instabilities, multiphase flow, solid dynamics, flow in porous media, uncertainty quantification and photonics. Our Front Tracking code, FronTier, has been extended to three dimensions, and is now functioning robustly for the simulation of three-dimensional complex fluid mixing flows. We have made a major effort in the study of multiphase flow, including a proposed model of averaged multiphase flow equations which seem to avoid most of the well known pitfalls for such equations. Validation studies for the Front Tracking code, FronTier Solid have been performed. Photonics, a new project for this work, is conducted in collaboration with C. Bowden of Redstone Arsenel, and a group of his collaborators. We have developed a parallelized FDTD code to allow simulations in complex 3D geometries for photonic crystals and other photonic devices.
