Prediction of vinyl chloride drop sizes in stabilised liquid-liquid agitated dispersion

Stochastic Simulation of Droplet Interactions in Suspension Polymerization of Vinyl Chloride

“…Figure 3 represents the monomer droplet size distribution computed for impeller speed is 350 rpm and dispersed phase volume fraction is 0.3. Comparing that with the monomer droplet size distribution measured by Zerfa and Brooks [24] for the same parameter values the simulation data fit in really well with the measured data as it is seen in Fig. 3.…”

Representative drop sizes and drop size distributions in A/O dispersions in continuous flow stirred tank

“…Several studies report on direct proportionality between the Sauter mean diameter and maximum stable drop diameter (Brown and Pitt, 1972;Nishikawa et al,1987a;Collias and Pruddhornme, 1992;Zerfa and Brooks, 1996;Calabrese et al, 1986a). However, a few studies contradict this view (Zhou and Kresta, 1998;Sechremeli et al, 2006).…”

“…In many instances, direct proportionality between the two representative drop diameters has been reported (Brown and Pitt, 1972;Nishikawa et al, 1987a;Collias and Pruddhornme, 1992;Zerfa and Brooks, 1996;Calabrese et al, 1986a). Therefore, correlation for either of the representative diameters can be used to compute the other representative diameter.…”

A study of inverse dispersion polymerization of acrylic acid using water-soluble redox initiators

“…The drop coalescence and breakup are very complicated procedures and dependent not only on mixing conditions, but also on system internal properties. 13 The further coalescence and breakup of the coalesced drops could be restrained by the increase in the fluid viscosity inside the drops, owing to the formation of polymer molecules. However, the volume ratio of the reductant solution to the aqueous monomer is quite low (about 1 : 66), so that the aqueous reductant drops are unlikely to intermix with all aqueous monomer drops.…”
