The aim of the article is to study the uniformity of coating treatment with a liquid antiicing reagent using mathematical methods. The task of the modeling presented in the article is to formulate the basic principles for the development of mathematical and software monitoring systems for road and airfield machines for the distribution of reagents. To this end, a mathematical model for the motion of droplets of liquid anti-icing reagent in the air, taking into account the effect of the wind, as well as the physical properties of the medium under consideration is proposed. On its basis, the original program code is developed in the QtOctave environment. With the help of computer simulation, the influence of the height of the installation of the working part of the machine — the distribution disk — on the density of the spraying of the reagent was investigated. Using the capabilities of the software product QtOctave, the graphical dependence of the uniformity of the droplet distribution on the length of the treated zone on the wind speed is shown. The nature of the influence of the direction of motion of the air masses on the appearance of irregularity in the settling of the reagent drops on the coating is revealed. The graph and the results of calculations are presented confirming the absence of a connection between the rotational speed of the drive shaft of the disk and the deviation from the uniformity of the distribution of droplets in the process of anti-ice treatment of aerodrome and road surfaces. The obtained numerical and analytical results should be used in the work of monitoring systems, the main purpose of which is to ensure uniform dispersion of the reagent with a given range and flow rate.
Keywords: mathematical modeling, computer simulation, anti-icing reagent, drop of antiicing reagent (АR), uniform application of anti-icing reagent (AR) application, software product QtOctave, distribution zone.
