N2 - This basic conceptual study of dilute second-phase drop breakup in turbulent mixing vessels includes examination of (1) local viscous effects in the breakup of droplets smaller than the Kolmogoroff microscale, and (2) inertial effects in the breakup of droplets larger than the Kolmogoroff microscale. Particular emphasis is placed on the evaluation of local and spatial variability in the disruptive forces, and the local time and space scales of interest. For the second mechanism, a two-dimensional linear drop oscillation model is developed. Simulations using the model suggest that the critical Weber number may be a function of drop size, interfacial tension, viscosity, and the magnitude and duration of the disruptive force.
