Mathematical modeling of the breakup of laminar capillary jets
Abstract
A model describing the laminar breakup of a jet of Newtonian fluid issuing from a cylindrical tube is developed. It is shown how tube geometry can influence the breakup dynamics through the effect of the developing laminar velocity field, and through the generation of specific perturbations characteristic of the tube geometry. It is shown that the average drop size from a horizontal jet is influenced both by the laminar velocity field and the perturbations, while the average drop size from a vertical jet is determined primarily by the jet radius near the jet breakup point. The calculated results are compared with published experimental results.
