This book is intended to provide a compilation of the state-of-the-art numerical methods for nonlinear fluid-structure interaction using the moving boundary Lagrangian-Eulerian formulation. Single and two-phase viscous incompressible fluid flows are considered with the increasing complexity of structures ranging from rigid-body, linear elastic and nonlinear large deformation to fully-coupled flexible multibody system. This book is unique with regard to computational modeling of such complex fluid-structure interaction problems at high Reynolds numbers, whereby various coupling techniques are introduced and systematically discussed. The techniques are demonstrated for large-scale practical problems in aerospace and marine/offshore engineering. This book also provides a comprehensive understanding of underlying unsteady physics and coupled mechanical aspects of the fluid-structure interaction from a computational point of view. Using the body-fitted and moving mesh formulations,the physical insights associated with structure-to-fluid mass ratios (i.e., added mass effects), Reynolds number, large structural deformation, free surface, and other interacting physical fields are covered. The book includes the basic tools necessary to build the concepts required for modeling such coupled fluid-structure interaction problems, thus exposing the reader to advanced topics of multiphysics and multiscale phenomena.
Dr. Rajeev K. Jaiman is currently an Associate Professor and NSERC/Seaspan Industrial Chair in the Department of Mechanical Engineering at the University of British Columbia (UBC), Vancouver, Canada. An aeronautical engineer by training, his research concentrates on high-fidelity multiphysics modeling and data-driven computing, with emphasis on large-scale computations of fluid-solid and fluid-fluid interface problems. Prior to his current appointment at UBC, he was an assistant professor in the Department of Mechanical Engineering at the National University of Singapore (NUS). Before joining NUS, he was the Director of Computational Fluid Dynamics (CFD) Development at Altair Engineering, Inc., Mountain View, California. The CFD technologies that Dr. Jaiman has developed are routinely used in marine/offshore, wind turbine, nuclear reactors, automotive and aerospace industries. Dr. Jaiman earned his first degree in Aerospace Engineering from the Indian Institute of Technology, Mumbai. He received his master's and doctorate degrees from the University of Illinois at Urbana-Champaign (UIUC). He has authored/co-authored more than 150 journals papers and conference proceedings and serves as an expert reviewer for numerous journals and books. He is currently an Associate Editor of ASME-OMAE Journal, a senior member of AIAA and members of ASME, SNAME, USACM, APS, AAM, and SIAM. Dr. Vaibhav Joshi is currently an Assistant Professor in the Department of Mechanical Engineering at Birla Institute of Technology and Science (BITS) Pilani, K. K. Birla Goa Campus, Goa, India. His research focuses on high-fidelity computational modeling of fluid-structure interaction. Prior to his current association with BITS, he was a postdoctoral research fellow in the Department of Mechanical Engineering at The University of British Columbia (UBC), Vancouver, Canada. He was in-charge of the Computational Multiphysics Laboratory at UBC and worked on developing flexible multibody fluid-structure interaction framework for bio-inspired flying vehicles. Before joining as a post-doc, he carried out his doctoral studies at the National University of Singapore (NUS) and worked as a research engineer at the Keppel-NUS Corporate Laboratory. There, he developed a computational framework to model two-phase fluid-structure interaction, motivated by the coupled offshore vessel-riser system subjected to turbulent ocean current and free surface waves. He received his Bachelor of Technology degree in Mechanical Engineering from Vellore Institute of Technology University, Vellore, India.
