This book was released on 2018-12-29 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potential contamination of a spacecraft cryogenic surface by a xenon (Xe) ion generator was evaluated. The analysis involves the description of the plume exhausted from the generator with its relative component fluxes on the spacecraft surfaces, and verification of the conditions for condensation, adsorption, and sputtering at those locations. The data describing the plume fluxes and their effects on surfaces were obtained from two sources: the tests carried out with the Xe generator in a small vacuum chamber to indicate deposits and sputter on monitor slides; and the extensive tests with a mercury (Hg) ion thruster in a large vacuum chamber. The Hg thruster tests provided data on the neutrals, on low-energy ion fluxes, on high-energy ion fluxes, and on sputtered materials at several locations within the plume. Scialdone, John J.

Download or read book Experimental and Numerical Study of Spacecraft Contamination Problems Associated With Gas and Gas Droplet Thruster Plume Flows written by and published by . This book was released on 2006 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project consists of two large parts. The first part is the study of plume flows escaping into vacuum, and the second part deals with gasdroplet flows. These two parts are united by a common area of research, namely, contamination problems of space station surfaces due to thruster firing. The objective of the first part is accurate prediction of force and heat loads and contamination due to interaction of thruster plumes with the spacecraft surface. This requires a detailed knowledge of the plume structure. For this purpose, a software system SMILE (Statistical Modeling In Low-density Environment) is developed for modeling plume flows. This system is based on the Direct Simulation Monte Carlo (DSMC) method and incorporates economical numerical schemes of the DSMC method majorant frequency scheme, advanced models that describe energy transfer in the case of collisions of diatomic and polyatomic molecules, possibilities of parallelization, and models for chemically reacting flows of polyatomic gases. An important aspect associated with this activity is the use of advanced object-oriented approaches for the development of the SMILE system. The objective of the second part is an experimental and numerical study of a two-phase gas-droplet flow arising in the case of simultaneous exhaustion of liquid and gas into vacuum. This problem is closely related to the processes of backflow contamination of spacecraft surfaces by thruster plumes with a fuel film used for cooling the inner surface of the nozzle. The main attention is paid to studying the behavior of droplets into which the liquid is decomposed at the initial stage of droplet motion and to the interaction of droplets with a freely expanding gas plume.
