Abstract: The common theme of this research is to address the principle challenge and scientific issue in simulation of moving interfaces, especially free surface water waves, high Reynolds number flows and the fluid interaction with fixed and moving objects. Many large flexible structures exhibit unacceptable movement in water waves and wind fields. The fluid processes and the interaction between structure and fluid are typically nonlinear. Development of numerical models to accurately capture nonlinearities at the free surface is important in advancing research in ocean engineering and related sciences. This talk introduces and focuses on an alternative method to traditional numerical modeling, rooted in the Lattice Boltzmann equations, to examine the underlying physics of breaking waves, and bluff- body boundary layers. Highlight of achievements and work in progress will be demonstrated through a variety of test cases including the treatment of shocks (bores) and long wave run-up.

Biography: Jannette Frandsen received the B.Sc. from the Technical University of Denmark (1991) and the M.Sc. from Imperial College London (1996). She earned the doctorate at Cambridge University Engineering Department (2000). Hereafter she served as an assistant professor at Oxford and concurrently held a Junior Research Fellowship at Oriel College (1999- 2002). Then she moved to USA and joined Louisiana State University as Assistant Professor of Civil Engrg. (2002-2005). Currently, she is an Associate Professor at the University of Hawaii, Department of Ocean and Resources Engineering. Underpinning her academic experience, she also worked in industry (1988-1995) as a structural/ocean engineer where she got involved with analysis of fixed offshore platforms and semi-submersibles. Her research interests are in the areas of fluid dynamics, nonlinear free- surface water waves and fluid-structure interactions.
