Mixing and Segregation of Granular Materials
- J. Ottino, D. Khakhar
- Physics
- 2000
▪ Abstract Granular materials segregate. Small differences in either size or density lead to flow-induced segregation, a complex phenomenon without parallel in fluids. Modeling of mixing and… Expand
Radial segregation of granular mixtures in rotating cylinders
- D. Khakhar, J. J. McCarthy, J. Ottino
- Physics
- 1 December 1997
Simultaneous mixing and segregation of granular materials is of considerable practical importance; the interplay among both processes is, however, poorly understood from a fundamental viewpoint. The… Expand
A case study of chaotic mixing in deterministic flows: The partitioned-pipe mixer
- D. Khakhar, J. G. Franjione, J. Ottino
- Mathematics
- 1987
Abstract We exploit the connection between the kinematics of mixing and the theory of dynamical systems. The presentation takes the form of a case study of a novel continuous flow mixer—the… Expand
Scaling relations for granular flow in quasi-two-dimensional rotating cylinders.
- A. V. Orpe, D. Khakhar
- Medicine, Physics
- Physical review. E, Statistical, nonlinear, and…
- 27 August 2001
An experimental study of the flow of different materials (steel balls, glass beads, and sand) in quasi-two-dimensional rotating cylinders is carried out using flow visualization. The flow in the… Expand
Modeling of the Dynamics of Water and R‐11 blown polyurethane foam formation
- S. Baser, D. Khakhar
- Materials Science
- 1 April 1994
Polyurethane foam formation involves both polymerization and expansion processes. The dynamics of the water and R-11 blown foams depend on the rates of chemical and physical blowing processes, along… Expand
Modeling of the dynamics of R-11 blown polyurethane foam formation
- S. Baser, D. Khakhar
- Materials Science
- 1 April 1994
The dynamics of R-11 blown polyurethane foam formation depend on the rates of viscosity increase of the reacting mixture and R-11 evaporation, and both are controlled by the polymerization process.… Expand
Transverse flow and mixing of granular materials in a rotating cylinder
- D. Khakhar, J. J. McCarthy, Troy Shinbrot, J. M. Ottino
- Physics
- 1997
The focus of this work is analysis of mixing in a rotating cylinder—a prototype system for mixing of granular materials—with the objective of understanding and highlighting the role of flow on the… Expand
Surface flow of granular materials: model and experiments in heap formation
- D. Khakhar, A. V. Orpe, P. Andresén, J. Ottino
- Materials Science
- 25 August 2001
Granular surface flows are important in industrial practice and natural systems, but the understanding of such flows is at present incomplete. We present a combined theoretical and experimental study… Expand
Mixing and Dispersion of Viscous Liquids and Powdered Solids
- J. Ottino, P. DeRoussel, S. Hansen, D. Khakhar
- Materials Science
- 1999
Publisher Summary Mixing and dispersion of viscous fluids—blending in the polymer processing literature—is the result of complex interaction between flow and events occurring at drop length-scales:… Expand
Rheology of binary granular mixtures in the dense flow regime
- A. Tripathi, D. Khakhar
- Physics
- 9 November 2011
We study the rheology of granular mixtures in a steady, fully developed, gravity-driven flow on an inclined plane, by means of discrete element method (DEM) simulations. Results are presented for a… Expand
