WCPC Flow Schematic
  • Cooled saturator followed by warm condenser
    (growth tube)
  • In cooled saturator aerosol saturated with water
    vapor temperature equilibrated
  • Growth tube Heated walls produce high level of
    supersaturation as water vapor diffuses quickly
    to center of stream before aerosol is heated up
  • Mass diffusivity of water vapor gt
  • thermal diffusivity of air !
  • Aerosol becomes supersaturated and water
    condenses on particles
