Patent abstract
An apparatus and method for producing a region of vapor super-saturation and particle growth in a laminar flow by surrounding the particle flow with a saturated or super-saturated sheath flow from which vapor diffuses into the aerosol flow. This method is applicable when the mass diffusivity of the condensing vapor is greater than the thermal diffusivity of the carrier gas, such as is the case when water vapor diffuses into air.
