Porous Structures as Atomic Oxygen Trap (B03)

An improved collector efficiency for atmosphere-breathing electric propulsion systems can be achieved by using porous structures. The occurring rarefied non-equilibrium flows and sorption processes within porous structures will be described in detail microscopically using the particle-based DSMC code PICLas. Based on these findings, methods for efficient scaling to macroscopic structures will be developed and evaluated, realizing effective relationships between networks of pore bodies with a fast but faithful surrogate model.
