Modeling the Uniform Treatment of Coatings with an Anti-Icing Liquid Reagent

Abstract

The aim of this work is to study the uniformity of the treatment of coatings with an anti-icing liquid reagent using mathematical methods. The task of the modeling presented is to formulate the basic principles for the development of mathematical support and software for monitoring systems of road and airfield machines for the distribution of reagents. To do this, a mathematical model for the motion of droplets of a liquid anti-icing reagent in the air, taking into account the effect of the wind and the physical properties of the medium under consideration, is proposed. The original program code is developed based on it in the QtOctave environment. Using computer simulation, the influence of the height of the installed working element of the machine, i.e., the distributing disk, on the spraying density of the reagent is investigated. The QtOctave software product allows showing the plot of dependence of the uniform distribution of droplets over the length of the treated zone on the wind velocity. The character of the influence of the direction of the motion of air mass on the nonuniform settling of the reagent’s droplets on the coating is revealed. The calculation plot and results confirming the absence of relationships between the rotational speed of the drive shaft of the disk and deviation from the uniform distribution of droplets in the process of the anti-ice treatment of the airfield and road surfaces are presented. The numerical and analytical results should be used in the work of monitoring systems, the main purpose of which is to ensure the uniform dispersion of the reagent with an assigned range and flow rate.
