Impedance Measurements of Inertance Tubes for Pulse Tube Cryocoolers

Article Preview

Abstract:

The impedance of the inertance tubes which include the mass flows, pressure amplitudes and phase shifts between them at the inlet of the inertance tubes were measured by correcting the mass flows at the surface of the compressor piston. The experimental results are compared with the theoretical values based on simplified turbulent-flow thermoacoustic model. The wide range of impedance measurements with different inertance tube geometries and operating parameters enable us to summarize the general rules of their effects on impedance respectively, also the differences between the experiments and calculations can be used to modify the theoretical model.
