Abstract. A computational model describing the two-dimensional, turbulent mixing of a single jet of exhaust gas from aircraftengines with the ambient atmosphere is presented. The underlying assumptions and governing equations are examined andsupplemented by a discussion of analytical solutions. As an application, the jet dynamics of a B747-400 aircraft engine in cruiseand its dependence on key parameters is investigated in detail. The computer code for this dynamical model is computationallyfast and can easily be coupled to complex chemical and microphysical models in order to perform comprehensive studies ofatmospheric effects from aircraft exhaust emissions in the jet regime.
