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.
