The condensation coefficient is obtained by combining a shock tube experiment and the corresponding numerical analysis based on the Gaussian-BGK Boltzmann equation. In the experiment, the liquid film growth on the shock tube endwall behind the reflected shock wave is measured with a high accuracy by an optical interferometer. The interferometer system is improved, which enables us to combine the experiment and numerical analysis more closely. The results show that the condensation coefficient of methanol takes values from 0.7 to 0.9 in nonequilibrium states, and the values are close to that of evaporation coefficient evaluated by molecular dynamics simulations.
