Abstract
Acoustic standing waves in a tube filled with a vapor is theoretically analyzed. The wave motion is excited by a sound source mounted on an end of the tube, the other end of which is closed by a solid wall and a condensed phase of the vapor is formed on it. The evaporation and condensation is therefore induced by the wave motion. The phenomenon concerned is studied on the basis of an asymptotic method for the Boltzmann equation. The asymptotic analysis shows that the wave motion is governed by the linear wave equation in the bulk vapor phase and the heat conduction equation in a thermal boundary layer appears near the boundary. The standing wave is determined by solving the two equations.
