Energy conversion of thermoacoustic engines with evaporation and condensation

Autor: Mariko Senga, Shinya Hasegawa

Publikováno v: International Journal of Heat and Mass Transfer. 165:120385

This study investigated the energy conversion of a thermoacoustic engine using a wet regenerator for the interconversion of heat flux density and work flux density. According to the first law of thermodynamics, local energy conversion can be describe

Four-stage loop-type cascade traveling-wave thermoacoustic engine

Autor: Mariko Senga, Shinya Hasegawa

Publikováno v: Applied Thermal Engineering. 104:258-262

We designed and built a prototype of a loop-type cascade traveling-wave thermoacoustic engine with four regenerators. The objective with this prototype engine was to achieve both high acoustic impedance at the regenerator position and a traveling-wav

Thermal diffusion effect of a regenerator with complex flow channels

Autor: Mariko Senga, Shinya Hasegawa, Yutaro Ashigaki

Publikováno v: Applied Thermal Engineering. 104:237-242

The thermal diffusion effect caused by an oscillatory flow has a large effect on the thermal efficiency of a thermoacoustic engine. This study measures and compares the thermal diffusion effect caused by an oscillatory flow in regenerators with unifo
