Assessment of the Liquid Deicing Reagent Distribution Zone Deformation at Different Parameters of the Environment

The article considers distribution of liquid deicing reagents over aerodrome pavement. The deformation of the treatment zone contributing to the formation of unevenness of distribution under different environmental parameters (air temperature, wind speed and direction) is estimated. The research is based on the developed mathematical models of the reagent droplet movements over the distribution disk and in the air. The dependence of overlapping the two zones and the width of the untreated zone on the wind speed and direction is derived. The process of reagent distribution at different ambient temperatures and varying height of disks above the pavement is simulated. Estimation of quality indicators of anti-icing treatment for the temperature range from 0 to --15 °C is given on the basis of the obtained results. The practical value of the obtained results lies in the possibility of their application in the development of operational methods to ensure the quality of distribution of liquid chemicals under changing environmental conditions
