Study of Basic Theories of Water Condensation.

Abstract

A new growth equation for pure water and solution droplets with radii greater than or equal to about one micron has been developed. It differs from previous equations in that discrete vapor and temperature fields at the surface of growing droplets are considered. Inefficiency factors containing the accommodation and condensation coefficients are derived which control water vapor density and air temperature just above a droplet surface assuming steady state conditions. Previous growth and evaporation equations are critically reviewed and compared with the present theory. It is shown that previous equations can be derived from the new equation as special cases. The newly derived general expression is numerically evaluated and graphically examined for the case of pure water droplets. The present theory and equations may also be applied to the growth of an ice particle where the shape can be assumed to be spherical. (Author)
