Journal ArticleDOI
Ultrasonic fragmentation of agglomerate powders
TL;DR: In this paper, a theory for ultrasonic fragmentation of agglomerate particles suspended in liquids is presented, and an expression for the fragmentation rate as a function of ultra-osnic power and agglerate size is derived.
Journal ArticleDOI
Impact of fracture coatings on fracture/matrix flow interactions in unsaturated, porous media
TL;DR: In this article, a model combining Darcy's law and the Washburn equation has been used to describe the imbibition behavior of fracture-dominated groundwater flow in unsaturated, fractured rock.
Journal ArticleDOI
Energy—size reduction laws for ultrasonic fragmentation
TL;DR: In this paper, a semi-empirical expression that relates fragmentation rate to particle size, suspension volume and ultrasonic power was derived for both eroding and non-eroding powders.
Journal ArticleDOI
Determination of agglomerate strength distributions
TL;DR: In this paper, a characterization technique has been developed to quantitatively determine agglomerate strength distributions in bulk powders, which may be used throughout a powder processing procedure to determine the source of agglomers, as well as an aid in the elimination of these agglerates by helping the user to understand the nature of the interparticle bonds.
Journal ArticleDOI
Determination of agglomerate strength distributions Part 3. Application to titania processing
TL;DR: A quantitative agglomerate strength determination technique, consisting of exposing sample dispersion to a calibrated ultrasonic field and following the resultant changes via particle size analysis, was examined and developed in previous portions of this study as discussed by the authors.
