Abstract
In laser fusion experiment, fuel capsules with high sphericity and high wall-thickness uniformity are often fabricated by the emulsion method. To understand the process of forming the uniform wall by the emulsion method and to further improve the thickness uniformity, we formulated a model to simulate the centering process of a water globule in a compound emulsion. We newly added a thermodynamic force to the centering force in addition to previous hydrodynamic forces. Our result indicates that nonuniform emulsion turns to be uniform by repeating instantaneous deformations followed with continuous rotation around the horizontal axis.
