Chemical processes and materials are often governed by complex dynamics spanning a broad spectrum of length and time scales. Non-trivial coupling between them makes prediction of material properties or process outcome highly challenging, for which intuition can often be misleading. We use high-performance computers and combine a range of numerical tools -- including computational fluid dynamics (CFD) and molecular dynamics (MD) -- to simulate these systems and investigate their underlying dynamics, from the molecular scale up to the continuum level. Our recent efforts focus on two major areas. One is fluid mechanics, especially the non-linear dynamics of flow turbulence in polymer solutions and its application in energy-saving techniques. The other is polymer science, especially amorphous and network polymers and their transport, mechanical and rheological properties.
