Summary

Two standing-wave thermoacoustic engines with a constant-diameter resonant tube and a tapered one, respectively, are simulatedwith linear thermoacoustics to explore the reasons for performance improvement of the thermoacoustic engine with the tapered resonanttube substituting for the constant-diameter one. Computed results indicate that the viscous loss in the tapered resonant tube is muchlower than that in the constant-diameter one, and the smooth joint between the tapered resonant tube and its resonant cavity may avoidthe acoustic power loss derived from sharp variation of flow area. The comparison between the computed results and the experimentaldata indicates that the simulation can roughly predict the performance of thermoacoustic engines with these two types of resonant tubes.
