PRODUCTION OF UNIFORMLY SIZED DUAL CONCENTRIC DROPLETS FROM COAXIAL SMOOTH JET UNDER APPLIED AC ELECTRIC FIELD
RESUMO
Production of uniform-sized droplets by means of a mechanical vibration method and an electric AC method has been studied. The relationship between those two methods at the limits of the uniform region have not been established. The upper and the lower limits of the frequency of a uniform droplet region (synchronous region) for the mechanical vibration method and the AC electric field method were the same. From the analogy of surface wave propagation caused by mechanical and electrical vibrations, it is considered that the AC electric field may cause an initial disturbance or displacement on the electric conductive liquid surface. Thus the surface wave growth along the liquid column surface will result in synchronous disintegration of the smooth liquid jet. The generation of concentric dual droplets by the AC electric field method and surface wave propagation rates on coaxial dual liquid columns is discussed. This method may provide a new technique for the production of fine uniform droplets or particles, even for nonelectric conductive liquids.
