Aerosol-generating system comprising a cartridge with an internal air flow passage

An electrically heatable aerosol-generating system comprising an aerosol-generating device and a cartridge,

• the cartridge comprising:
• a cartridge housing comprising an inner wall and an outer wall, the inner wall being disposed within the outer wall and defining an internal passage through which air can flow, the inner wall and the outer wall defining a hollow space therebetween,
• an aerosol-forming substrate contained within the hollow space, and
• a susceptor element;
• and
• the aerosol-generating device comprising:
• a device housing defining a cavity configured to receive at least a portion of the cartridge,
• an inductor coil positioned in the device housing around or adjacent to the cavity and positioned outside of the cartridge when the cartridge is received in the cavity, and
• a power supply connected to the inductor coil and configured to provide a high-frequency oscillating current to the inductor coil, wherein a magnetic field generated by the inductor coil causes generation of heat in the susceptor element of the cartridge.
