Abstract

The nonlinear resonant gas oscillation excited in a one-dimensional space between an oscillating plate and a planer surface of a thin liquid layer on a quiescent rigid-wall is considered. In particular, we focus on the case where the vapor is a polyatomic gas, e.g., water, the liquid is its own condensed phase and no other species of molecules are included. The vapor is initially in an equilibrium state at rest. The plate harmonically oscillates at a resonant frequency in the system and induces a sound wave. The behavior of gas with evaporation or condensation at the interface is analyzed by applying the asymptotic theory for small Knudsen number on the basis of polyatomic version of Gaussian-BGK Boltzmann equation and a kinetic boundary condition for the interface.
