| 内容記述 | The recontamination of a spacecraft surface directly exposed to the ram flux is investigated. It is assumed that the surface has been contaminated by a rocket plume contact and that, subsequent to the exposure, the contaminated surface is placed in the ram flux. A BGK-simulation was compared to both a Direct Simulation Monte Carlo (DSMC) and a Full Flow Monte Carlo (FFMC) using sensitivity analysis. Results indicate that the BGK-based simulation underpredicted the return flux contamination as compared to both the DSMC and FFMC techniques. Results from the full flow model suggest that the BGK model is inadequate to represent this physical problem. |
