Abstract
An apparatus and method for producing a diffusive, continuous laminar flow for particle growth via condensation of vapors with a mass diffusivity near or higher than the thermal diffusivity of the surrounding gas. In an exemplary embodiment, the method uses the condensation of water vapor onto particles suspended in air.
