A Comparison of Measured and Computed Energy Exchanger Performance,

Abstract

Measurements and numerical modeling of energy exchanger flow and performance have been carried out to characterize controlling processes and to maximize the efficiency of a small test device. An energy exchanger is a rotating, axial flow wave machine in which unsteady gas dynamic processes are used to directly transfer work between initially high and low pressure streams. A laboratory scale energy exchanger was developed and tested under steady flow conditions to study sensitivity to a number of flow and configuration parameters. This machine operated at a pressure ratio of approximately 2.5 and transferred approximately 100 kW of power between two impedance matched streams.
