Abstract
An inertialess jet containing Newtonian drops in a gravitation-free field has been modeled by incorporating the detailed micro-structural dynamics. Interactions of the drops with the continuous phase, with the wall, and with the jet surface are accounted for, thereby eliminating the need for additional constitutive assumptions. The deformation of the jet and drops, and the dispersion of drops are predicted. The present paper serves two purposes. First, a complete description of the modeling process and its limitation is presented. Second, preliminary results for single and for small clusters of drops indicate the potential inherent in this computational approach. The model flow is solved in two dimensions using the boundary element method (BEM). Effects of different drop parameters, such as their number, relative position, and interfacial tension are investigated.
