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

Abstract

The analysis adopted to determine the parameters affecting the maximum performance of the ballistic-piston compression process is divided into two cases. A heavy piston treatment, which con siders the charge gas compression to be poly tropic, is presented for compressions in which the irreversibilities induced into the charge gas by pressure waves may be considered negligible. If the entropy increases associated with these waves are not negligible as light piston analysis is required. The experimental results of the liquid driven piston system, in which the charge gas is rapidly compressed as it decelerates a high speed column of water, have demonstrated that pressures in excess of water hammer can be achieved. Hence, it is seen that the piston, in addition to providing a means of separating the liquid driver and charge gas, enables higher pressures to be achieved than the impact pressure in the driver fluid.
