| Abstract: | The water vapor subcooling limit in homogeneous nucleate condensation is determined in the present paper by using density fluctuation theory of statistical thermodynamics. In conclusion, the mechanism of water vapor nucleate condensation is much more complicated than the mechanism of liquid nucleate boiling. It is predicted that the influence of kinetic effects is very important to the vapor nucleate condensation. |
