Characteristics of Liquid Atomization by the Internal Mixing Twin-Fluid Atomizer(I) -Effect of Geometry of Mixing Chamber-

摘要

In order to clarify the influence of the geometry of the mixing cham- ber on the atomization by the internal mixing twin-fluid atomizer, several flow patterns in the mixing chamber, which were caused by the change of the mixing chamber geomet- ry, were photographed and the Sauter mean diameter was measured by the Fraunhofer diffraction technique. The change of the mixing chamber length has en effect on the flow pattern within the mixing chamber and the Sauter mean diameter of a spray issued from the atomizer.
