Hierarchical Modeling and Simulation Techniques with Application to Computational Fluid Dynamics and Fluid-Flow Control

Abstract

The primary research objective of this contract was to investigate and develop fluid flow control procedures by utilizing a hierarchical modeling approach. This project included research on control and identification methods for vortex wakes, with the primary example being stabilization of vortices behind a flat plate. Vortex blob and finite difference methods were constructed to provide the flow dynamics. Linear time-invariant feedback controllers have been developed, as well as identification results for a class of input/output models that can be used to design more sophisticated controllers. Additionally, Java based software components that support hierarchical modeling efforts were created.
