摘要：

Condensation can occur by the nucleation and growth of water droplets on particles in the air. This mode of mass transport can readily occur in a thermal boundary layer. The primary condition required for droplet nucleation is the existence of supersaturation in the boundary layer. Equations are developed to describe droplet nucleation and transport for the boundary layer on a horizontal, upward facing surface. These equations allow diffusion and nucleation mass fluxes and droplet concentration at a point in the boundary layer to be calculated. Experimental data were collected and compared to the theoretical calculations. Accurately predicting droplet concentration is difficult, but the presence of nucleation condensation can be readily predicted.
