INVESTIGATIONS OF BALLISTIC-PISTON AND LIQUID DRIVEN PISTON COMPRESSORS FOR THE PRODUCTION OF HIGH TEMPERATURE AND HIGH DENSITY GASES

摘要

Research on systems for the production of high temperature and high density gases is being conducted by the University of Dayton Research Institute to determine the feasibility of various pressure energy exchange apparatus to produce isolated high temperature and high pressure gas. The subject of this technical note is the theoretical analysis and experimental test program con-ducted to gain insight into the operation of ballistic-piston compressors, and the continuation of effort toward the development of liquid driven gas compression systems.nThe analysis adopted to determine the parameters affecting the maximum performance of the ballistic-piston compression process has been divided into two cases. A heavy piston treatment, which considers the charge gas compression to be polytrophic, is presented for compressions in which the irreversibility’s induced into the charge gas by pressure waves may be considered negligible. If the entropy increases associated with these waves are not negligible a light piston analysis is required.
