Document Type and Number:
Japanese Patent JP3276150
Kind Code:
B2
Abstract:
Liquid to be atomized is uniformly sprayed on the inner surface of a hollow rotating cylinder, for example by means of one- or two-fluid-nozzles and is thus distributed on apertures provided in the cylinder wall. The rotation of the cylinder causes the liquid to flow outwards through the apertures. Droplets are generated when the liquid flows out of the apertures by laminary decomposition of the jet. The flow rate in each aperture lies in the range 1.0<{dot over (V)}A (a3rho5/sigma5)0.25<16 to prevent the droplets from becoming too large and to satisfy the condition of an adequate flow laminarity, i.e. for the value of the Reynolds Number for the continuous liquid flow in the apertures not to exceed Redelta 400. {dot over (V)}A represents the flow rate of the liquid in each aperture, a represents the centrifugal acceleration at the outer surface of the cylinder, rho represents the density of the liquid, and 8 indicates the surface tension of the liquid. The large number N>200 of apertures having the diameter DA in the cylinder wall causes the flow rate of liquid through each aperture to be relatively low, so that a continuous laminary flow in each aperture is ensured even at low viscosities and technically useful total flow rates.
