Abstract : Research on a pressure energy exchange principle, conducted to determine the feasibility of various pressure energy exchange apparatus to produce isolated high temperature and high pressure gas is described. The theoretical analysis and test results of a 200 atmosphere gas driver system and the development of a liquid driver system are emphasized. The test results of the 200 atmosphere gas driver system, which utilizes the work of expansion of a high pressure driver gas to compress an initially low pressure charge gas, are compared with a thorough theoretical analysis. Severe mixing of the driver and charge gases has been found to degrade the performance to such an extent as to regard the system tested as inadequate for the production of high temperature, high pressure pure air. The initial results of a liquid driver system, in which the charge gas is rapidly compressed as it decelerates a high speed column of liquid, indicate that this concept is worthy of future development. Studies are also discussed which were directed towards tailoring a tube or nozzle to eliminate Taylor instability for use in systems in which mechanical separation is not desirable. (Author)
