Aerosol-generating article having an air channelling element with inner and outer air passageways

An aerosol-generating system comprising an aerosol-generating article for producing an inhalable aerosol upon heating and an aerosol-generating device comprising a heating chamber, the aerosol-generating article being configured to be received within the heating chamber and comprising:

• a rod of aerosol-generating substrate;
• a downstream section located downstream of the rod of aerosol-generating substrate, the downstream section comprising a downstream air channelling element abutting a downstream end of the rod of aerosol-generating substrate, wherein the downstream air channelling element comprises a body comprising a core portion and a peripheral portion circumscribing the core portion, wherein the peripheral portion extends between the outer periphery of the air channelling element and the core portion, the core portion comprising one or more inner air passageways and the peripheral portion comprising one or more outer air passageways, wherein a total cross-sectional area of the one or more outer air passageways is greater than a total cross-sectional area of the one or more inner air passageways;
• and
• a ventilation zone located along the downstream air channelling element, wherein the ventilation zone establishes a fluid communication with the one or more outer air passageways;
• wherein the aerosol-generating device comprises a heater configured to externally heat the rod of aerosol-generating substrate.
