Lecture Title: Immersed Boundary Methods-Translating Concepts into Simulations
Abstract: The last 25 years have seen a phenomenal growth in the application of Immersed Boundary Methods (IBMs) to the computational modeling of fluid flows. The power of IBM lies in the fact that it frees the fluid dynamicist from the need to generate body-conformal grids, thereby allowing rapid translation from concepts to simulations. The very early applications of the IBM were in the areas of interfacial and biological fluid dynamics, and while these remain the strongholds for these methods, application have expanded to encompass most areas of fluids dynamics including fluid-structure interaction, multiphase flows, acoustics, fluidic microdevices, heat transfer, design optimization, reacting flows and others. This expanded scope has also been accompanied by significant numerical and computational advancements in these methods. In my talk I will review the history as well as the state-of-the-art of IBMs. The particular emphasis of my talk will be on some areas that have been the focus of my own research in recent years: IBMs with improved accuracy and conservation properties, and application to biological flows, bioacoustics, and fluid-structure interaction.
