Will present a talk titled:
Application of Finite Volume Method for Surface Water Flow Modeling
Abstract: This seminar presents the application of finite volume method to solve the three-dimensional Navier-Stokes equations and the depth-averaged two-dimensional shallow water equations for simulating free-surface water flows in rivers, estuaries, and coastal zones. Numerical discretization is based on quadrilateral, quadtree rectangular, and hybrid meshes. The velocity-pressure coupling is achieved through the SIMPLEC algorithm with underrelaxation and Rhie and Chow’s momentum interpolation on non-staggered grid systems. The free surface is tracked by using the volume-of-fluid (VOF) method in the three-dimensional model. The discretized equations are solved using the SIP algorithm for structural grids and the GMRES algorithm for unstructural grids. Selected application examples include tidal flow, dam-break flow, and tsunami-structure interactions.

Bio: Dr. Weiming Wu is James K. Edzwald Professor of Water Engineering, Civil and Environmental Engineering Department, Clarkson University, USA. He earned his PhD from Wuhan University of Hydraulic and Electric Engineering, China in 1991. He was an Alexander von Humboldt Research Fellow at the University of Karlsruhe, Germany in 1995–1997, and a faculty at the National Center for Computational Hydroscience and Engineering, University of Mississippi in 1997–2013. His research interests include hydraulics, sediment transport, dam/levee breach, water quality, and aquatic ecosystems in rivers, estuaries, and coastal zones. He has developed a series of one-, two- and three-dimensional models for flow and sediment transport in riverine and coastal waters, as well as dam/levee breach models. Dr. Wu is the author of two books “Computational River Dynamics” (2007) and “Sediment Transport Dynamics” (2023), and has published over 150 journal and conference papers. He is a Fellow of American Society of Civil Engineers (ASCE) and International Association of Hydro-Environmental Engineering and Research (IAHR). He served as Associate Editor for International Journal of Sediment Research in 2008-2010 and for ASCE Journal of Hydraulic Engineering in 2010-2019, as well as Chair for ASCE/EWRI Computational Hydraulics Committee (2010-2012), Task Committee on Dam/Levee Breaching (2009-2012), and Sedimentation Committee (2016-2018). He currently serves as Chair for ASCE/EWRI Hydraulics and Waterways Council and Vice President for World Association of Sedimentation and Erosion Research (WASER).
