RESEARCH FIELD / CONTENTS
Compared to traditional thermodynamic researches mainly dealing with equilibrium systems, recent advanced thermodynamic and statistical mechanical approaches have been attempted to analyze various physical behaviors of complex organic/inorganic materials at nonequilibrium states such as polymeric systems under external flow fields. In conjunction with these nonequilibrium thermodynamic approaches, many theoretical, experimental, and computational studies have been conducted to understand the heat, mass, and momentum transport phenomena for complex fluid systems. In particular, significant advances in methodological development of multiscale computer simulations together with the rapid increase in computing power have recently made it possible to explore the fundamental microscopic molecular origins underlying the general macroscopic physical properties and phenomena of complex polymeric systems, thereby elucidating the structure-property-processing relationships.
