Direct measurement of the effect of adhesion on powder flow behavior
Abstract
<p>The current study adapts a novel approach to directly measure the effect of particle adhesion on the bulk powder flow characteristics. This is achieved by modifying the adhesion of spherical glass particles (mean size: 38 μm) through a protocol that involves the deposition of surface silane monolayers on individual glass particles. The increase in particle surface energy has been characterized by particle-particle pull off force measurements using Atomic Force Microscopy. An annular shear cell has been used to measure flow properties and to quantify the effect of surface energy of the silanized glass particles on their bulk cohesion. Computer simulations using the Distinct Element Method (DEM) have also been carried out. The DEM simulations use JKR adhesion model to incorporate the surface energy values of glass beads corresponding to the AFM pull-off force measurements. The Unconfined Yield Stress (UYS) and Flow Factor (ff) obtained by the simulations have been compared with the experiments.</p>
