Abstract: The paper discusses calculation methodologies based on using maximum flow principle for centrifugal nozzles, and analyzes both their advantages and disadvantages. Basing on fundamental physical dependencies a mathematical model of viscous fluid flowing through atomizer of centrifugal nozzle is described. The results of research of the influence of atomizer geometry, surface roughness and fluid viscosity on nozzle characteristics are demonstrated. It is also shown that the developed mathematical model for fine spray nozzles calculation allows to obtain the results that agree well to the data of the bench test carried out with water and viscous fluid (till 30 cPz)

Abstract: The paper discusses the parameters that characterize the fineness of liquid atomization with centrifugal atomizers. It is shown that the parameter „average diameter” and „average zauther diameter” used by the manufacturer without specifying the adopted distribution function of droplets by diameters makes it difficult for consumers to choose nozzles available on the market. The distribu-tion functions of Rosin-Rammler and Tresh-Golovkov for centrifugal atomizers are compared, and the ratios between the characteristic diameters of the droplets spectrum for these distributions are presented. The results of the study can guide the consumers in the characteristics of the fineness of atomization claimed by the manufacturers of the injectors and cited by authors in scientific and technical literature
