【Abstract】 A traveling wave thermoacoustic engine consisting of a looped tube and a resonator has been successfully designed and constructed.The process of self sustained thermoacoustic oscillation in present heat engine is described and analyzed by phase space distribution reconstructed from the time series of acoustic signals.The onset characteristic and shift of traveling wave mode to standing wave mode of oscillation in thermoacoustic engine are investigated experimentally.更多还原
