Numerical Simulations of Complex Multiphase Flows
Dr. Gretar Tryggvason is the Charles A. Miller, Jr. Distinguished Professor at the Johns Hopkins University and the head of the Department of Mechanical Engineering. He received his PhD from Brown University in 1985 and was on the faculty of the University of Michigan in Ann Arbor until 2000, when he moved to Worcester Polytechnic Institute as the head of the Department of Mechanical Engineering. Between 2010 and 2017 he was the Viola D. Hank professor at the University of Notre Dame and the chair of the Department of Aerospace and Mechanical Engineering. Professor Tryggvason is well known for his contributions to computational fluid dynamics; particularly the development of methods for computations of multiphase flows and for pioneering direct numerical simulations of such flows. He served as the editor-in-chief of the Journal of Computational Physics 2002-2015, is a fellow of APS, ASME and AAAS, and the recipient of several awards, including the 2012 ASME Fluids Engineering Award and the 2019 ASTFE Award.
CFD Insights Ship Flows and Structural Interaction
Dr. Frederick Stern is a Professor at Department of Mechanical Engineering and IIHR, University of Iowa. He is an expert in experimental/computational ship hydrodynamics following an integrated approach: experiments guided by simulations provide validation data and simulations fill in sparse data. Iowa towing tank/wave basin data have been used for physics, CFD validation, and test cases for CFD workshops and NATO AVT working groups. CFDShip-Iowa URANS/DES is one of the best codes at CFD workshops since 1994 with many functionalities. Next generation high-fidelity/resolution V6 enables two-phase sharp-interface DNS/LES utilizing billions of grid points. Research includes development of V&V and UQ methods, fundamental physics, ship performance, deterministic/stochastic multi-disciplinary optimization, and fluid structure interaction, as described in many publications.
Multiscale Simulations of Liquid Crystalline Materials
Dr. Grecov received her Ph.D. in Fluid Mechanics from Grenoble Institute of Technology. After a postdoctoral research fellow position at McGill University, Montreal, she joined the University of British Columbia, Vancouver, in 2005, where she is a Professor in the Department of Mechanical Engineering. Her expertise is in modeling and simulations, biofluid mechanics, non-Newtonian fluid mechanics, rheology and tribology. She has more than 20 years of experience in complex fluids research, constitutive modeling development, and numerical simulations. She received the CFI (Canada Foundation for Innovation) Leaders Opportunity Award in 2007, a Peter Wall Early Career Scholar Award in 2007, the NSERC (Natural Sci. & Eng. Res. Council) Discovery Accelerator Award in 2016, the Wall Scholars Research Award in 2016 and she is a fellow of Engineers Canada from 2019. Dr. Grecov has published over 120 conference and journal papers, many of which are in prestigious journals. Her published papers are the outcome of the combination of analytical or/and experimental with numerical simulations. She has chaired many sessions at international conferences and advised more than 60 graduate and undergraduate students.
