EXPERIMENTAL INVESTIGATIONS ON NUCLEATION AND DROPWISE CONDENSATION OF WATER VAPOR BY MEANS OF A PEX-TUBE

pages 294-299

Abstract

The piston expansion tube (pex-tube), a new instrument for nucleation and droplet growth studies in supersaturated vapors is applied to water vapor. Nucleation rates in the temperature range 240 K - 285 K are measured for water vapor carried in air as well as for pure vapor. The nuclei grow into monodispersed droplets. Examples for the measured growth rates are presented in comparison with model calculations.
