Abstract
An aerosol generation system having an aerosol generator wherein a liquid formulation is at least partially volatilized in a capillary passage and discharged from the capillary passage to form an aerosol. The aerosol generation system includes a pumping unit adapted to supply a liquid formulation to the aerosol generator; and a fluidic element located between the pumping unit and the capillary passage of the aerosol generator, wherein the fluidic element increases backpressure of the liquid formulation as the liquid formulation enters the capillary passage of the aerosol generator.
