Kinetic theory of onedimensional evaporation and condensation problem
Abstract
A linearized Boltzmann equation with BGK collision model is solved using halfrange Hermite polynomials. The solution is applied to the study of halfspace evaporation and condensation problem. The validity of the analysis is confirmed by the comparison with other existing results. From the present result, it is more convincing to interpret that the mass flux rate is caused by the microscopic pressure jump at the interphase surface rather than the macroscopic one maintained between the saturated vapor and the vapor gas outside of the Knudsen layer.
