The possibility of performing a liquid phase compression in closed cycle gas turbine through the use of particular working fluids is discussed. From the results of calculations carried out for different fluids there is evidence that efficiency of the resulting cycle is considerably higher than that of regenerative Brayton cycles and comparable with that of regenerative Rankine cycles. The working fluid selection is recognized as the major problem in view of practical applications. Available data strongly support the conclusion that fluids meeting the needed requirements, at least for moderate temperature operation, can be found. Nuclear power stations appear to be one of the most promising fields of application of the liquid phase compression cycle.
