Particle Deposition onto Enclosure Surfaces

Abstract

In space applications, the main concern of particle deposition arises from the undesirable effects of surface obscuration on contamination-sensitive surfaces. The development of effective mitigation strategies to minimize particulate contamination requires the understanding of particle transport and deposition as well as the associated physical factors affecting the processes. The knowledge gleaned from the state-of-the-art literature review presented here can be applied to an enclosure scale as small as a spacecraft payload cavity, or as large as a clean room in a manufacturing/processing facility. The insights from studying the physical processes that influence the rate of particle deposition within an enclosure are expected to provide a strong scientific foundation to benefit various aspects of aerospace contamination control needs.
