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.

Capillary system with fluidic element

An aerosol generator includes a flow passage having an inlet end, an outlet end, and a constriction in the flow passage at the outlet end. A heater is operable to heat liquid in the flow passage to produce a vapor, which is expelled from the outlet end of the flow passage.
