Emission inventories analysis at European and Ukrainian airports highlighted that aircraft is a dominant source of air pollution. To evaluate the aircraft contribution in airport air quality, it is important to consider some features of the aircraft, as a special source of air pollution. For the most part of landing-take-off cycle, the aircraft is maneuvering on the ground, and it is subjected to fluid flow that can create a strong vortex between the ground and engine nozzle, which have essential influence on structure and basic mechanisms of exhaust gases jet from aircraft engine. The paper demonstrates the results of CFD modeling and analysis for the jets close to ground surface, simulating the aircraft engine jets’ performances in airport. The numerical simulation of wall jet by Fluent 6.3 was implemented for different combination of initial jet velocity and height of engine installation to evaluate the influence of the ground on jet’s parameters (height and longitudinal coordinate of buoyancy effect, length of jet penetration). Obtained results provide improvement of PolEmiCa model.
