Feedback form is now closed.
A porous medium made with ceramics is set inside a resonator and the acoustic dissipation occurring in it is measured. Two conditions are tested. One is that the wall of the porous medium is wet by water, and the other is that it is dry. Measured results show that water does not affect dissipation caused by velocity oscillation; however, it affects the dissipation caused by pressure oscillation. Furthermore, it is found that the effect of water increases with the temperature of the working gas. A theory that can consider the effect of condensation and evaporation on sound propagation is used to investigate the result.
