Deformation and fragmentation of non-Newtonian liquid droplets is investigated using an Eulerian-Eulerian, volume-of-fluid (VOF) interface capturing technique. It is found that the breakup behavior of shear thinning, non-Newtonian liquid droplets is drastically different as compared to their Newtonian counterparts. Several flow features commonly exhibited by non-Newtonian fluids are observed during the breakup process. The breakup initiates with the formation of beads-in-a-string. This is followed by rapid rotation of the droplet with the appearance of helical instability and liquid budges, which forms the sites for primary and satellite droplet shedding. Child droplet size distributions are also examined and it is found that a Gaussian function universally characterizes the droplet sizes produced during the breakup of a single non-Newtonian droplet.
