Abstract

We describe a two-dimensional simulation of burst in neutrally buoyant drops subject to shear using a two-component, two-speed lattice Bhatnager-Gross-Krook (BGK) fluid. Measuring the dependence of critical shear rate for drop rupture on flow parameters, our results validate the method over a range of simulation variables. The model's interfacial tension parameter sigma, undeformed drop radius, and BGK relaxation parameter omega are all found to have the correct influence upon the process of burst required by simple hydrodynamic theory. Within the model, the macroscopic surface tension and fluid. viscosity are coupled; however, this does not limit the application of the technique.
