A thermoacoustic Stirling heat engine.
Author(s) : BACKHAUS S., SWIFT G. W.
Type of article: Article
Summary
The authors demonstrate an inexpensive thermoacoustic engine that employs the inherently efficient Stirling cycle. The design is based on a simple acoustic apparatus with no moving parts. Their first small laboratory prototype, constructed using inexpensive hardware (steel pipes), achieves an efficiency of 0.30, which exceeds the values of 0.10-0.25 attained in other heat engines with no moving parts. Moreover, the efficiency of their prototype is comparable to that of the common internal combustion engine (0.25-0.40) and piston-driven Stirling engines (0.20-0.38).
