Talk Title: Computational Fluid-Structure Interaction: Methods Developed and Advanced Simulations Performed

Series: Aerospace and Mechanical Engineering Seminar Series

Abstract: The presentation is focused on the computational framework that involves coupling of fluid and structural mechanics, where structures undergo large deformations. The formulation of fluid mechanics on the moving domain is presented, and efficient solution strategies for the underlying linear equation systems are discussed. A framework for computational fluid-structure interaction (FSI) based on the Arbitrary Lagrangian-Eulerian formulation is presented. Basics of Isogeometric Analysis are also shown. The fluid-structure interface discretization is assumed to be nonmatching allowing for the coupling of standard finite-element and isogeometric discretizations for the fluid and structural mechanics parts of the FSI problem, respectively. FSI coupling strategies and their implementation in the high-performance parallel computing environment are also discussed, and computational challenges presented. Applications ranging from cardiovascular mechanics to full-scale offshore wind turbines are presented.

Biography: Prof. Bazilevs received his PhD from the Institute for Computational Engineering and Sciences at the University of Texas at Austin in 2006, and he is currently a Full Professor and Vice Chair in Department of Structural Engineering at University of California, San Diego. He has published nearly 100 archival journal papers on computational fluid and solid/structural mechanics, and fluid-“structure interaction. He coauthored a book on isogeometric analysis, a methodology that is now widely used in computational mechanics. He also coauthored a book on computational fluid-structure interaction. He is an Associate Editor of Elsevier journal Computers and Fluids and Assistant Editor of Springer journal Computational Mechanics for the manuscripts on computational fluid mechanics and fluid-structure interaction.
