Problem Definition: The influence of emissions caused by ablation/demise on the atmosphere and is directly dependent on the propagation of those residuals along the flight path. The investigation of the temporal and spatial distribution of the generated emissions in the atmospheric layers after the re-entering launch vehicle has passed through is therefore crucial for drawing conclusions about their climate impact.
Research Objectives:
- Definition of a suitable interface region based on the results from other IRP
- Numerical analysis of the emission propagation in the near field of the re-entering vehicle
- Multiscale simulations of the downstream expansion behaviour of the residuals for different atmospheric layers
- Definition of suitable interfaces to process data for the climate models
Expected Results:
- Ability to assess the influence of demise process on the release of emissions into different atmospheric layers
- Numerical model to describe the temporal and spatial dispersion behaviour of ablated gases in the atmosphere
- Derivation of parameters necessary for the calculation of regional atmospheric effects
Secondments:
- von Karman Institute for Fluid Dynamics (VKI, Sint-Genesius-Rode, Belgium, ca. 3 months): definition of common model interfaces
- Astos Solutions GmbH (ASTOS, Stuttgart, Germany, ca. 3 months): coupling with trajectory profiles
