Abstract

The space-time fluid-structure interaction (FSI) techniques developed by
the Team for Advanced Flow Simulation and Modeling (T*AFSM) are being used
for some of the most challenging FSI problems, including parachute
modeling and arterial FSI. We summarize the core numerical technologies of
the space-time FSI techniques, and describe the enhancements and special
supplementary techniques introduced recently by the T*AFSM to increase the
scope and efficiency of these techniques. The special FSI techniques
include interface projections techniques, such as the Homogenized Modeling
of Geometric Porosity (HMGP), and multiscale sequentially-coupled FSI
techniques. We present a number of 3D numerical examples computed with
these space-time FSI techniques, including the FSI modeling of the
parachutes to be used for the Orion spacecraft.
