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