The statistics of the deformation and breakup of neutrally buoyant sub-Kolmogorov ellipsoidal drops is investigated via Lagrangian simulations of homogeneous isotropic turbulence. The mean lifetime of a drop is also studied as a function of the initial drop size and the capillary number. A vector model of a drop previously introduced by Olbricht et al. ( J. Non-Newtonian Fluid Mech. , vol. 10, 1982, pp. 291–318) is used to predict the behaviour of the above quantities analytically.
