A COMPARATIVE STUDY OF STEADY AND NONSTEADY-FLOW ENERGY SEPARATORS
Abstract
This paper analyzes and compares two methods of energy separation -- a steady-flow method proposed by Ranque over thirty years ago and a nonsteady- flow method recently proposed and studied by Foa. Part I of the paper develops a simple theory for devices utilizing the first method (Ranque tubes). Despite its simplicity and extreme idealization, the theory appears to provide better agreement with experimental data than any of the available analytical treatments. Part II is an extension of the Foa theory of the non-steady-flow energy separator. The extension is more idealized than the original theory but covers a wider variety of embodiments of the concept. A comparison is also given between the performance characteristics of steady-flow and non-steady-flow energy separators. Part III defines a coefficient of performance for the two devices as refrigerators or air conditioners, and compares these coefficients with those of standard refrigerating cycles.
