A bubble population balance model is proposed for the prediction of Sa
uter mean bubble diameters in mechanical notation cells. In the model,
the notation cell is treated as two separate, statistically homogeneo
us zones-the impeller zone, and the bulk tank zone. Balance functions
for the rates of bubble breakage, coalescence, recirculation and inlet
-outlet events are proposed based on classical chemical engineering re
search in two- and three-phase fluid mixing systems. An initial simula
tion of the population balance model shows trends in bubble size distr
ibutions comparable to measured distributions in industrial mechanical
notation cells.
