报告摘要:

This presentation summarizes some of our recent research works in the field of multiphase flow simulation. The modelling strategies we employed include both grid-based and particle-based methods, to support a diverse range of applications ranging from fresh concrete placement in construction industry to visual effect generation in movies and video games. Multiphase flow phenomena are very common in both natural environment and engineering systems. Examples include debris flow, bubbles, oil & gas flow, boiler combustion, and water treatment etc. A multiphase flow system typically contains at least one continuum phase that is highly flowable, and it can be in either gas or liquid form. Besides the continuum matrix phase, it also contains at least one added phase, which can be in solid, gas or liquid forms. The behaviour of a multiphase flow system is largely determined by the various interactions among difference phases, which can take place in the form of either physical interaction or chemical reaction. It is these complex physical-chemical interactions that bring a major challenge to the modelling of multiphase flow systems.

报告人简介:

Professor Chenfeng Li obtained his BEng and MSc degrees in 1999 and 2002 respectively, from Tsinghua University, China, and he obtained his PhD degree in 2006 from Swansea University, U.K. His research centres largely on computational engineering including both computational solid mechanics and computational fluid dynamics. Besides this main theme of research he is also very much into uncertainty quantification and computer graphics, both underpinned by computer simulation. His research interest include problems in civil & structural engineering, geomechanics, oil & gas reservoir, concrete, composite and other heterogeneous materials. He has published over 60 peer reviewed papers and is currently the Editor for Engineering Computations.
