フライホイール型熱音響エンジンの出力と効率の測定

抄録

We analyze the rotation frequency of a flywheel-based traveling-wave thermoacoustic engine from the energy balance between the energy supply from the loop tube and the energy dissipation in the piston-crank-flywheel assembly. The energy supply from the looped tube was calculated numerically using the result of the thermoacoustic theory, and the energy dissipation in the piston-crank-flywheel assembly was determined from measurement of rotation angle during freely rotating state without the influence of the looped tube. Finally, we found that the operating frequency was in good agreement with that the engine made of the looped tube and the piston-crank-flywheel assembly under investigation.
