Coagulation and fragmentation: Universal steady-state particle-size distribution
TL;DR: A population balance model presented describes simultaneous coagulation and fragmentation during shear-induced flocculation of polystyrene particles and indicates that the steady-state floc-size distribution is self-preserving with respect to fluid shear.

Sung Jae Chung,Sung Jae Chung,J.P. Leonard,J.P. Leonard,Ian Nettleship,Ian Nettleship,Jung-Kun Lee,Yee Soong,Donald V. Martello,Minking K. Chyu,Minking K. Chyu +10 more
TL;DR: In this paper, a submersible accelerometer probe was used to measure the relative ultrasonic energy field in the liquid for various ultrasonication methods, and the dispersion of ZnO was found to proceed by a fragmentation process, with minimum achievable particle size in the range 50 to 300 nm.

Simultaneous coagulation and break-up using constant-N Monte Carlo
Kang Taek Lee,Themis Matsoukas +1 more
TL;DR: In this paper, a new Monte Carlo method for solving the population balance problem with multiple growth processes is presented, which samples a constant number of particles regardless of whether the actual growth process results in increase or decrease of the particle concentration.
Journal ArticleDOI
Agglomerates and aggregates of nanoparticles made in the gas phase
TL;DR: In this paper, an analysis of the properties of agglomerates and aggregates in terms of their volume-equivalent radius, radius of gyration and/or mobility radii in the free molecular and continuum regimes along with the corresponding power laws is presented.

Theoretical kinetic model for particulates disintegration processes that result in bimodal size distributions
L.M. Popplewell,Micha Peleg +1 more
TL;DR: In this article, a model for disintegration in general and erosion-dominated processes in particular is presented, where a large particle from which fines have been detached is allowed to remain, at least temporarily, in its original size slot, and the breakage frequency of the particle population is described by a bimodal β-distribution.
