Title

Numerical Simulation of a Widely Used Cloud Nucleus Counter

Abstract

The performance of the conventional horizontal plate thermal diffusion chamber as a cloud nucleus counter was studied. Numerical calculations were performed in order to follow the simultaneous drop growth and sedimentation in the spatially and temporally nonuniform supersaturation field. The effect of nuclei distribution and smallest detectable drop size were investigated. The results indicate order of magnitude uncertainty in the count at 0. 1% supersaturation, and a factor of 2 uncertainty at 1. 0% supersaturation.
