Processes of dispersion of working liquid jets in electro droplet-jet technology: numerical simulation

The essence of the Electro Droplet-Jet Technology (EDJT) consists of the production of a linear sequence of monodisperse droplets of a fluid, separated from each other by equal distances. Numerical simulation of a liquid jet dispersion and a two-phase droplet flow problem were performed. The effect of the computational mesh on the predictions was investigated; in particular, the influence of the angle of the cylinder sector on the processes of the jet breakup. The computation for the jet dispersion into monodisperse droplets due to the forced harmonic disturbance of the velocity field with the oscillation frequency was made. Then the calculation for the meshes with the various numbers of cells was performed. Similar computations were made for working liquids with various viscosity and surface tension coefficients.
