SF-86-05-4 -- An Investigation of the Compressor Slugging Phenomenon PDF

This paper presents the results of a preliminary experimental and analytical investigation of the slugging induced overpressures often encountered in refrigerant compressors. The experimental aspect of the project involved instrumenting a representative compressor, and then operating it under simulated slugging conditions. For the analytical study, two computer simulation programs were developed for the examination of the compressor processes under slugging-like conditions. Experimental and analytical results compare favorably as the trends and the qualitative features have been found to be similar.
