Abstract
For the spray of a single-component fluid (water) from a simplex atomizer, dependences of the mean size, mean velocity, and frequency of droplet registration on the pressure and method supplying the power fluid into the simplex channels were obtained by the local time-shift method using a SpraySpy device. Visual analysis of the effect of adding a fluid (kerosene) immiscible at the molecular level with water on the structure and decay of the spray cone was carried out by shadow photography. It was found that the two-component emulsion disintegrates in the close proximity of the atomizer outlet orifice almost at once, resulting in significant deformation of the spray cone.
