✦ Synopsis

Heat ¯ow and work ¯ow are the basic concepts in thermoacoustic phenomena, both of which are introduced by the thermal interaction between the oscillating ¯uid and solid component. We have developed an experimental technique to determine the work ¯ow in a thermoacoustic device and applied it to a thermoacoustic engine consisting of a looped tube and a resonator. We have found that the reliable determination of the work ¯ow requires the proper evaluation of various correction terms, including the time lag involved in the pressure and the velocity measurements of the oscillating ¯uid.
