Peking University, Aug. 23, 2012: On August 20, Chen Shiyi , professor from the College of Engineering, PKU, gave an invited lecture on the opening ceremony of the 23rd International Congress of Theoretical and Applied Mechanics (ICTAM2012).

As the largest and most influential global event in the Mechanics community, ICTAM2012 has gathered over 1500 distinguished experts and scholars in Mechanics from 66 countries and regions of the world to share the recent updates in all Mechanics-related fields in Beijing on August 19-24 .

ICTAM was founded in early 1920s under the suggestion of renowned scientist Theodore von Kármán. With its first session held in Delft, Holland, in 1924, it is then held every four years and regarded as the “Mechanics Olympics”, serving as the largest platform facilitating the academic development in mechanics. Chen is the first Chinese scholar to deliver an opening lecture in the 90 years’ history of ICTAM.

In the lecture entitled “Multiscale Fluid Mechanics and Modeling”, Chen pointed out that multiscale phenomena of fluid dynamics are ubiquitous in nature and multi-scale modeling will play an important role in the new discovery of fluid physics and engineering application. Chen then introduced two multi-scale modeling methods based on the idea of physical constraints: a hybrid continuum and molecular method to simulate micro- and nano-fluid flows and Reynolds Stress Constrained Large Eddy Simulation (RSC-LES) which can be used to simulate many engineering problems including aerodynamics. Their results have demonstrated the capability of multiscale simulation methods for complex fluid systems and the necessity of physical constraints on the multiscale methods.

Chen received his M.S. and Ph.D. in Mechanics from Peking University in 1984 and 1987, respectively. He then spent many years doing research in U.S., mostly in Los Alamos National Laboratory and Johns Hopkins University (JHU). He served as chair of the Department of Mechanical Engineering of JHU before taking his current position in 2005. His research interests include Statistical theory and computation of fluid turbulence, Mesoscopic physics and lattice Boltzmann computational Methods, Molecular dynamics and granular flows, Computational fluid dynamics and numerical analysis.
