A wire mesh regenerator is studied, with one end closed and the other subject to a harmonic variation of flow. The methods of linear wave analysis are used to determine acomplex input admittance, Y, for the system. Y is the ratio of volume flow to pressure excess for a given frequency, and permits piston face pressure waveform to be determined directly in terms of prescribed velocity waveform. A computational procedure is developed for finding the pressure waveform at the closed end. Computed waveforms are presented and discussed. Energy dissipated per cycle is calculated.
