A model for turbulent binary breakup of dispersed fluid particles

Water Model and CFD-PBM Coupled Model of Gas-Liquid-Slag Three-Phase Flow in Ladle Metallurgy

“…The PBE is written in terms of volume fraction of bubble size i: The breakage formulation for the discrete method in this work is based on the Hagesather method. 36) And it is assumed that there is no breakage for the smallest bubble class.…”

Modeling the breakup of fluid particles in turbulent flows

“…It is assumed that for each there is a distribution of fluctuating velocity and the normalized energy distribution is given by 9 :…”

“…One of the refinements was done by relaxing criteria of the upper integration limit. 9 Martinez and colleagues proposed a model that uses no restriction on the eddy scales. However, that model contains an empirical parameter.…”

“…Therefore, although the breakup model by Luo is the most widely used model and has been adopted by numerous authors, the use of different breakup models with DSD functions that contain the capillary constraint (Lehr et al, 2002) or prefer the equal-sized breakup (Alopaeus et al, 2002;Martínez-Bazán et al, 1999) should be considered. Besides, modifications of the Luo model that restrict the formation of small bubbles have been proposed (Hagesaether et al, 2002;Wang et al, 2003). These models will be studied together with the local BSD in detail in the upcoming work of the authors.…”
