CFD methods for three-dimensional computation of complex flow problems

This paper provides an overview of some of the CFD methods developed by the Team for Advanced Flow Simulation and Modeling (T*AFSM) [http://www.mems.r ice.edu/TAFSM/]. The paper also provides many examples of three-dimensional flow simulations carried out with these CFD methods and advanced parallel supercomputers. The methods and tools described in this paper include: stab ilized finite element formulations; formulations for flows with moving boun daries and interfaces; mesh update methods; iterative solution techniques f or large nonlinear equation systems; and parallel implementation of these m ethods. Our target is to be able to address effectively certain classes of flow simulation problems. These include: unsteady flows with interfaces; fl uid-object interactions; fluid-structure interactions; airdrop systems; aer odynamics of complex shapes; and contaminant dispersion.
