Mixing of powders and granular materials of different functions and/or properties is
frequently encountered by engineers and scientists. Nevertheless, the guidelines for the …

Discrete particle simulations provide a powerful tool for the advancement of our
understanding of granular media, and the development and refinement of the multitudinous …

This paper quantitatively and qualitatively evaluates the mixture and segregation processes
in an unbaffled rotary drum induced by particle size and density differences. We also …

The die filing process within a lab-scale rotary tablet press is simulated using the Discrete
Element Method (DEM). Powder is transferred from a gravity feeder (comprising of a …

Segregation of granular mixtures in the Freeman FT4 rheometer, a specific example of the
more general process of segregation induced via a rapidly rotating object, is studied. The …

Segregation refers to the separation of components in a powder mixture, resulting in
potential issues related to concentration inhomogeneity. Any well-mixed blend that …

Dry-granular material flowing on rough inclines can experience a self-induced Rayleigh-
Taylor (RT) instability followed by the spontaneous emergence of convection cells. For this …

Driving and controlling the segregation in a rotary drum is both a theoretical and a practical
challenge in powder technology. A novel horizontal split drum design composed of two …

Driving and controlling the segregation of particles with different properties in a rotary drum
is theoretical and challenging work in powder technology. In this work, a novel split drum …

Background: Cell adhesion is a process that involves the interaction between the cell
membrane and another surface, either a cell or a substrate. Unlike experimental tests …
