Seminar in Applied Mathematics

Dilhan Kalyon Department of Chemical, Biochemical, and Materials Engineering Stevens Institute of Technology Simulation of structure development and processing of highly filled materials Monday, December 6, 1999 3:00pm Morton 105

Abstract:   Materials filled at solid loading levels which are very close to the maximum packing fraction of the solid phase are encountered widely in various industries, including the pharmaceutical, food, ceramic, magnetic, composite, energetic, personal care, battery, and polymer industries. At such high solid loading levels the rheological characterization, continuous processing, mathematical modeling and analysis of the microstructural distributions of highly filled dispersions and suspensions become very challenging. In this talk the important facets of the rheology and continuous processing of highly filled suspensions, including their wall slip, mat formation, air entrainment, viscoplasticity, structure formation, and specialized simulation techniques, will be reviewed. Various tools of dynamics adapted to describe the mixing occurring in the confines of the continuous processors will also be described and typical results will be shown.
