Abstract
An aerosol generator includes a composite conduit to transport multiple liquids to a heating element at flow rates such that the liquids arrive at the heating element in desirable concentrations. The heating element volatilizes the liquids to form volatilized fluid, which mixes with ambient air to form an aerosol with desirable concentrations of the multiple liquids.
