CFD simulation of exhaust gases jet from aircraft engine

The growth of world aviation traffic leads to an increase of the impact on the environment that is now becoming one of the main factors determining the development of the aviation industry. Computational fluid dynamics (CFD) has become an attractive tool to predict pollutant concentration in the real environment. CFD software represents the most advanced mathematics that can be applied to simulation different physical process, including the transfer and dilution of fluid flow from aircraft, vehicle and other sources. This paper is an attempt to compare numerical simulation results of exhaust gases jet from aircraft near aerodrome surface by three CFD codes: Fluent 6.3, OpenFOAM and Solid-Works. The work is also focused on assessment of the aerodrome surface influence on jet's parameters (height and longitudinal coordinate of buoyancy effect) and on providing of initial data for further dispersion modeling. The obtained results are also aimed to improve complex model PolEmiCa. (C) 2020 Elsevier Ltd. All rights reserved.
