Singularities in droplet pinching without viscosity
نویسنده
چکیده
A model for the pinching of an inviscid liquid column, originally developed by Lee, is considered. We find that Lee’s model has a singularity in the curvature at a finite thread radius, and therefore does not describe breakup. However, the observed steepening of the profile corresponds to experiments with fluids at low viscosity. The singularity has similarity form, which we compute analytically. The result agrees well with numerical simulations of Lee’s model.

Singularities in Droplet Pinching with Vanishing Viscosity
A slender-jet model for the pinching of a liquid column is considered in the limit of vanishing viscosity. We find the model to develop a singularity in the gradients of the local radius and the velocity at a finite thread radius, so it does not describe breakup. However, the observed steepening of the profile corresponds to experiments and simulations with fluids at low viscosity. The singular...
متن کاملStudy of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios
In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...
متن کاملStudy of Cylindrical Jet Breakup Using One-Dimensional Approximations of the Euler Equations
We study the phenomenon of pinching of inviscid incompressible jets when surface tension is important. This is done by analyzing one-dimensional models derived by use of slender jet theory. Equations are derived for both singleand two-fluid arrangements. Higher-order terms are retained for regularization purposes. In the absence of a surrounding fluid these equations are the inviscid Cosserat s...
متن کاملThe effect of fluorescent tracers on droplet spectrum, viscosity, and density of pesticide formulations.
The most important factor affecting efficacy and drift of pesticide applications is the droplet spectrum. To measure pesticide drift, researchers utilize fluorescent tracers to rapidly quantify spray deposition. Although fluorescent tracers have been used for more than 50 years, no experiments have been performed on the effect they have on the properties of pesticide formulations (density and v...
متن کاملAppeared in Communications in Pure and Applied Mathematics volume 51, pages 733–795, 1998. SINGULARITY FORMATION IN THIN JETS WITH SURFACE TENSION
We derive and study asymptotic models for the dynamics of a thin jet of fluid that is separated from an outer immiscible fluid by fluid interfaces with surface tension. Both fluids are assumed to be incompressible, inviscid, irrotational, and density matched. One such thin jet model is a coupled system of PDEs with nonlocal terms – Hilbert transforms – that result from expansion of a Biot-Savar...
