Item Drop Breakup in Stirred-Tank Contactors. Part III: Correlations for Mean Size and Drop Size Distribution.(1987) Calabrese, Richard V.; Wang, C.Y.; Bryner, Nelson P.; ISRIn Part II, the extent to which dispersed-phase viscosity and interfacial tension influence equilibrium mean drop size and drop size distribution was determined for dilute suspensions produced in baffled cylindrical tanks of standard geometry equipped with six-blade Rushton turbines. Low to moderate viscosity dispersed- phase systems behaved similarly in that Sauter mean diameter could be correlated using the mechanistic arguments of Part I, and drop sizes, normalized with respect to D_32, could be correlated by a normal distribution in volume. Limited moderate viscosity data were reported in Part I but were not used to develop the correlations of Part II. The objective of this study is to combine the low to moderate viscosity data of Parts I and II with those obtained by other investigators to obtain correlations of broader utility, and to extend these via mechanistic arguments so that they apply to nondilute systems.Item Drop Breakup in Turbulent Stirred-Tank Contactors. Part II: Relative Influence of Viscosity and Interfacial Tension.(1987) Wang, C.Y.; Calabrese, Richard V.; ISRThe relative influence of dispersed-phase viscosity and interfacial tension on equilibrium drop size and drop size distribution is studied for dilute suspensions by dispersing various silicone oils in water, methanol, and their solutions. Correlations for Sauter mean diameter, D_32, are developed in terms of syatem variables using the mechanistic models of Part I. Drop sizes for low to moderate viscosity dispersed phases are normally distributed in volume and can be correlated by normalization with D_32. Trends in the distributions are explained in terms of a parameter representing the relative resistance to breakage.
