Problem Definition: The influence of rocket engine emissions on the atmosphere and thus the climate is directly dependent on the propagation of the engine plume along the flight path. The investigation of the temporal and spatial distribution of the exhaust gases in the atmospheric layers after the launch vehicle has passed through is therefore crucial for drawing conclusions about their climatic influence.
Research Objectives:
- Definition of a suitable interface region based on the results from DC8
- Numerical analysis of the plume propagation in the near field of the nozzle outlet
- Multiscale simulations of the downstream expansion behaviour of the engine exhaust plume for different atmospheric layers
- Definition of suitable interfaces to process data for the climate models
Expected Results:
- Ability to assess the influence of the engine plume on the release of emissions into different atmospheric layers
- Numerical model to describe the temporal and spatial dispersion behaviour of engine exhaust gases in the atmosphere
Secondments:
- Centre Euopéen de Recherche et de Formation Avancée en Calcul Scientifique (CERFACS, Toulouse, France, ca. 4 months): interface definitions and adaptions of numerical models
- Institute Pierre-Simon Laplace (IPSL, Guyancourt, France, ca. 2 months): interface tuning and simulations for plume-in-grid models
