Model of evaporation of kerosene droplets in the atmosphere and pollution of soil around the airfield

Pollution of soils near airport territories is caused by formation and dispersion of kerosene droplets during its incomplete combustion in afterburner operation of the aircraft engine. With constant impact on the environment even small amounts of unburned fuel over decades of operation of airfields (primarily military), the contribution of this component to soil contamination becomes no less significant than with emergency discharges. The description of kerosene dropping is based on the fact that the exhaust gases of aircraft engines and drainage systems cannot condense, as they are at temperatures above the critical temperature for kerosene. To condense, they are to become vaporized. Cooling of exhaust gases and condensation of kerosene vapors occurs with a high level of air flow turbulence. As a result, gas-dynamic formations with different mass are formed reaching condensation temperatures, turning into drops of liquid kerosene. Taking into account the set of random processes occurring during turbulent cooling of kerosene, droplet size distribution is Gaussian...
