Abstract: | The aim of this paper is to provide an investigation, using large eddy simulation, into plume dispersion behind an aircraft
in co-flowing take-off conditions. Validation studies of the computational model were presented by Aloysius and Wrobel (Environ
Model Softw 24:929–937, 2009) and a study of the flow and dispersion properties of a double-engine aircraft jet was presented
by Aloysius et al. (EEC/SEE/2007/001, EUROCONTROL Experimental Centre, ), in which only the engine was modelled. In this paper, the complete geometry of a Boeing 737 is modelled and investigated.
The current work represents a contribution towards a better understanding of the source dynamics behind an airplane jet engine
during the take-off and landing phases. The information provided from these simulations will be useful for future improvements
of existing dispersion models. |
