INFLUENCE OF THE SURFACE TENSION OF A LIQUID ON THE CHARACTERISTICS OF THE CONE OF ITS SPRAYING BY AN EJECTION ATOMIZER

Novel experimental data have been presented on the infl uence of the surface tension of a liquid on the dispersity of droplets in the spray cone of an ejection atomizer with forward and swirling gas feeds. The droplet-size distributions were measured with the optical method of small angles of the indicatrix of scattering. A decrease of nearly 10–17% in the median diameter of droplets of distilled water in the spray cone has been demonstrated with reduction in the coeffi cient of surface tension of water as a result of adding surfactants to it.
