“…This can evaluate the quality of atomization and determine the droplet properties. One of the main and characteristic diameters is the mean droplet diameter, called the Sauter diameter [2,30]. The Sauter mean diameter is, by definition, the ratio of the third to the second moment of the probability density function [31]…”

“…The Sauter diameter is very often applied because it allows for the characterization of many important processes, including determining the efficiency and rate of heat and mass transfer [2]. There are equations in the literature for swirl atomizers that can predict the mean droplet diameter.…”

“…Atomization process characteristics also include the analysis of the internal structure of spray, defined by the distribution of liquid in a spray. This is particularly important due to the selection of the proper atomizer type for a specific application [2,35]. Liu et al [35] have studied the constructions applicable to the fuel atomization.…”

This paper presents the results of experimental studies on two-phase conical swirl atomizers. The impact of various atomizer geometries and different operational parameters of the atomization process on the spray characteristics was investigated. The influence of the mixing chamber height HS to diameter DS ratio and the volumetric flow rates of liquid and gas on the discharge coefficient values, spray angle, droplet size expressed by Sauter mean diameter D32, volumetric and radial distributions of droplet diameters in the spray stream were determined. The analysis of results showed that the discharge coefficient values depend on the Reynolds number for liquid and gas and the atomizer geometry. The spray angle increases as the flow rate of liquid and gas increases depending on the applied atomizer construction. The Sauter mean diameter value is correlated with the geometric dimensions of the atomizer swirl chamber. The rapid increase in D32 occurs after exceeding the value HS/DS ≈ 3. The Sauter mean diameter also depends on the operating parameters. A central area of stream is filled with smaller sized droplets as the gas flow rate increases.
