| Abstract;The present paper aims at determining the condensation coefficient of water based on molecular gas dynamics analysis and shock tube experiment in weak vapor-liquid nonequilibrium states. The results show that, when the ratio of vapor pressure to saturated vapor pressure at the interface is close to unity, values of condensation coefficient of water equal to the value of evaporation coefficient estimated by the resent molecular dynamics analysis. As the ratio becomes large, the condensation coefficients decrease. The pressure ratio dependency of a condensation coefficient is explained by the molecular gas dynamics analysis. (author abst.) |
