Oscillatory Flow in Thermoacoustic Sound Wave Generator : Fluid Work in Stack and Resonance Tube

Abstract

Oscillatory flow in the thermoacoustic sound wave generator is described. In oscillatory pipe flow, characteristic Richardson effect occurs in the vicinity of the wall. Its flow plays an important role in thermoacoustic phenomena in which direct energy conversion from heat to work (sound waves), and vice versa, is performed with no moving parts. Also, flow in the resonance tube is influenced by its flow on the stack. Fluid work in stack and the resonance tube are discussed.
