Weakly nonlinear thermoacoustics for stacks with slowly varying pore cross-sections [PDF]
A general theory of thermoacoustics is derived for arbitrary stack pores. Previous theoretical treatments of porous media are extended by considering arbitrarily shaped pores with the only restriction that the pore cross-sections vary slowly in the ...

Modeling and controlling the generator of a thermoacoustic stirling engine [PDF]
Proceedings of the 3rd International Workshop on Thermoacoustics, 2015 The acoustic waves consist of alternating pressures and flows. The used generator is a linear generator that converts acoustic waves into electric power. The linear movement of the generator is limited; exceeding these limits might damage the generator.
