Maximum stable drop size as a function of maximum local energy dissipation rate ϵ
. ϵmax calculated on the basis of ϕ = ϵmax/ϵØ based on the measurements. Dispersion of paraffin oil in 1 mM PO4-buffer at pH 7.3. Maximum stable drop size measured after 3 h agitation. Geometries for different reactor configurations according to Table 2. Code for different aeration rates: +-center: 0.1 vvm, full symbol: 0.4 vvm, open symbol: 0.7 vvm, x-center: 1.0 vvm. Solid line: Theoretical prediction based on Eqs. 1 and 2, values for ϕ from Table 5. Dashed lines: plus/minus 20% deviation from theoretical prediction.
