Aerosol-generating system including solid and liquid aerosol-forming substrates

An aerosol-generating system comprising:

• a cartridge comprising a cartridge housing, a solid aerosol-forming substrate within the cartridge housing, and a porous carrier material within the cartridge housing and holding a liquid aerosol-forming substrate, the cartridge housing and the porous carrier material defining an airflow channel therebetween, a downstream end of the airflow channel being in fluidic communication with the solid aerosol-forming substrate;
• a heater section separate from the cartridge, the heater section comprising an electric heater and a liquid transfer element configured to contact the porous carrier material when the aerosol-generating system receives the cartridge, the porous carrier material being configured to circumscribe the liquid transfer element when the aerosol-generating system receives the cartridge;
• and
• an aerosol-generating device comprising a device housing and a power supply within the device housing, the device housing configured to receive the cartridge, and the power supply configured to supply electrical power to the electric heater.
