Daughter bubble size distribution

The experimental data of Risso and Fabre [99] also indicate that an equal size daughter distribution is more common for bubble breakage than an unequal one. Contrary, Hesketh et al [33, 34] investigated bubble breakage in turbulent flows in horizontal pipes and concluded that an unequal size daughter distribution is more probable than an equal size one. The daughter bubble size distribution model of Luo and Svendsen [74] rely on the assumption that unequal sized is more probable than equal size breakage in accordance with... 

Note that the units of the discrete daughter bubble size distribution variable are different from the units obtained deriving the continuous daughter size distribution function from the microscopic formulations (l/[m]). It is thus not trivial how to adopt the model of Luo [73] within a more fundamental modeling approach.
