Design and initial application of double-nozzle emulsion particle generator

A double-nozzle emulsion particle generator is developed to synthesize monodispersed ICF capsules. The working principle of the generator, the key designed parts, and idea for it are described. With this set-up, the reliability of double-layer particle encapsulation is increased simply by adjusting the concentricity of the three-layer tubes at the nozzle. Initial experiments show that monodispersed double-layer emulsion particles can be easily synthesized, and the flow-velocity ratio of oil phase to water phase, at which double-layer emulsion particles would be formed, ranges from 0.3 to 15.0.
