Abstract

The objectives of this thesis are to (i) investigate and further validate the Viscous Cell Boundary Element Method for more complex fluid mechanics problems and moving bodies and (ii) to use fundamental ideas of image processing and spectral methods to investigate the ability to inverse model the physical phenomena of data generated by the fluid code or any experimental data and to reduce successfully the system to a much smaller substitute that encapsulates the main physics of the original system. Lastly we aim to design a controller to use in open-loop flow control coupled with the fluid solver. The controller is designed by reduction of the equations describing the system.
