| Research Abstract |
Objective of this study was to achieve a novel development on a Stirling engine technology by replacing oscillating solid pistons with oscillations of a gas column or with oscillations of a liquid column. The looped tube type thermoacoustic engine, which had been invented as a pistonless Stirling engine based on unstable oscillations of the gas column, was modified in this study by using a co-axial tube consisting of cylindrical tubes with different diameters. Also, in this study, a pistonless-Stirling engine was developed by using oscillation of a liquid column in a U tube. This type of the engine operates at significantly low frequency compared with that using oscillation of a gas column.
