Abstract

Droplet breakup in homogeneous shear flow at super critical Capillary numbers and a viscosity ratio of unity is studied using a lattice Boltzmann method. We find that the total number of child drops that form from an isolated super critical drop scales according to a power law relation (n = 3.5). The child drops that form are all below critical, but not wholly uniform in size, and the distribution appears to be log-normal at high drop numbers. It is also found that for large ratios of the Capillary number to its critical value, the total strain required to break up a drop into N sub-critical entities tends to a constant value.
