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