"A Seamless Approach to Multiscale Simulation of Complex Fluids"

[This seminar is co-sponsored by the CREST Center for Mesoscopic Modeling and Simulation]


Dissipative particle dynamics (DPD) is a mesoscopic simulation method between molecular dynamics and continuum hydrodynamics. It can simulate efficiently complex liquids and dense suspensions using only a few thousands of virtual particles and at speed-up factors of more than one hundred thousands compared to molecular dynamics. We will demonstrate the potential and accuracy of the method by computing well known scaling laws for polymer flows from DPD simulations on a laptop.


Professor Karniadakis received his S.M. (1984) and Ph.D. (1987) from Massachusetts Institute of Technology. He was appointed a Lecturer in the Department of Mechanical Engineering at MIT in 1987 and subsequently he joined the Center for Turbulence Research at Stanford / Nasa Ames. He joined Princeton University as Assistant Professor in the Department of Mechanical and Aerospace Engineering and as Associate Faculty in the Program of Applied and Computational Mathematics. He was a Visiting Professor at Caltech (1993) in the Aeronautics Department. He joined Brown University as Associate Professor of Applied Mathematics in the Center for Fluid Mechanics on January 1, 1994. He became a full professor on July 1, 1996. He has been a Visiting Professor of Ocean Engineering at MIT since September 1, 2000.


Current research interests include diverse topics in computational science both on algorithms and applications. A main current thrust is stochastic simulations of physical and biological systems.
