dc.description.abstract | The breakup of a charged liquid column is studied numerically using Volume-OF-Fluid (VOF) for a range
of timescales where electrokinetic phenomena may become significant, i.e when the time to breakup
becomes comparable or shorter than the diffusion and the electroosmotic migration times of charged
species. Here we propose a conservative method to deal with the diffusion of a tracer in VOF schemes
when the diffusion is limited to one of the phases. The method consists in weighing the diffusivity with
the value of the volume fraction computed from the analytically reconstructed interface. In this way, the
interface is made impermeable to the tracer, which is conservatively kept within one of the phases. The
performance of this method is first tested by comparing simple configurations with existing analytical
solutions. In the cases when the diffusion, electroosmotic motion and hydrodynamic singularities com pete, the results indicate that, after breakup, charges distribute between droplets differently from models
assuming homogeneous and constant electrical conductivities (i.e. no electrokinetic effects). However,
such departure does not alter the main hydrodynamic balances leading to well-established scaling laws
of breakup. | es |
