| Outline of Final Research Achievements |
The formation of compound droplets from a co-axial dual nozzle, where core and shell fluids are imposed, is simulated numerically by a three-fluid front-tracking method. The modes of droplet formation depends on the diameter of the orifice ahead of the nozzle, the flow rate of the shell fluid, and that of the external fluid. The volume of core droplet as well as compound droplet itself suddenly increases as the flow rate of shell fluid increases beyond a critical value. The flow rate of shell fluid can be one of the control parameters for the size of compound droplets.
