The onset temperature of the thermoacoustic engine is required to bring down in respect of utilizing waste heat. Tsuda reported that the onset temperature is 343K when water vapor exist in the thermoacoustic engine. However it does not investigate the influence that adding water vapor gives in the temperature distribution in the stack of the thermoacoustic engine. In this study, we measured the temperature distribution in the stack of the thermoacoustic engine having wet stack after drive was starting and stable. The result of this experiment indicates that the temperature distribution in the wet stack becomes the curve of the convex.
