Incorporation of Aggregate Breakup in the Simulation of Orthokinetic Coagulation

Modeling of Oxidation-Driven Soot Aggregate Fragmentation in a Laminar Coflow Diffusion Flame

“…A summary of different fragmentation patterns proposed so far was given by Kim and Kramer (2007). Examples include the binary pattern (two fragments with a specific mass ratio; Spicer & Pratsinis, 1996), the normal pattern (a normal distribution of the fragments; Coulaloglou & Tavlarides, 1977;Spicer & Pratsinis, 1996), and the random pattern (random fragments; Kramer & Clark, 1999). Because the exact fragmentation pattern of a soot aggregate is not well known, as a first start, we examined in this study the binary pattern, which is the easiest one to implement and has been commonly used in aggregate fragmentation modeling (Spicer & Pratsinis, 1996).…”

Development of Novel Crystallizer Design and Optimization Tools for Solution Crystallization

“…Starting from the same basic considerations, but using a simpliÿed approach, Kramer and Clark (1999) developed another hydrodynamic breakage model for solid aggregates. They classiÿed failure modes by deÿning manifestation, induction and location of the failure, and stated that aggregates break when the maximum eigenvalue of the stress tensor is greater than the aggregate strength ( f ).…”

Modeling particle-size distribution dynamics in a shear-induced breakage process with an improved breakage kernel: Importance of the internal bonds

“…Hydrodynamic shear is employed in most flocculation system in order to assure a high collision frequency between particles for a rapid particle size growth [1,2]. However, if the agitation is too vigorous, the shear stress will be beyond the floc strength, which will break large flocs to small ones [3,4]. Since individual particles experienced different interactions, breakage is often random for particles of all sizes.…”

“…The breakage kernel is the rate coefficient for breakage, and breakage daughter distribution function defines the probability distribution by fragmentation. Breakage kernel is commonly considered as a power law function of the shear rate, G, and the aggregate size l [3,21].…”
