On flows of complex fluids: Colloidal dispersions, melt-mixing, and interface rheology

Research output: Contribution to journalArticle

Abstract

Most complex fluids are characterized different disparities: disparity of sizes of components as in colloidal dispersions, disparity of viscosity typically found in blends, disparity of relaxation times, and so on. Furthermore, most complex fluids are characterized by specific properties of interfaces. One important application of the rheology of complex fluids is melt-mixing process as used in polymer industries, food processing and pharmaceutical industries. We present a summary on our studies including a direct numerical simulation for colloidal dispersions in complex solvents which is called "Smoothed Profile method" (Phys. Rev. E 71, 036707 (2005);Phys. Rev. Lett.,96, 208302 (2006);Eur. Phys. J. E, 26, 361 (2008)), a characterization of melt-mixing process in a twin-screw extruder (Chem. Eng. Sci., 66, 103 (2011)), and dynamic shear response of melt polymer-polymer interfaces (Nihon Reoroji Gakkaishi, 40, 245 (2012)).
