An atomizing assembly is provided for an aerosol-generating system. The atomizing assembly comprises a tubing section having an inlet end and an outlet end. The inlet end of the tubing section is configured to be connected to a liquid storage portion, and the outlet end of the tubing section is in fluid communication with an atomizing nozzle. The tubing section is configured for delivering a flow of liquid aerosol-forming substrate through the atomizing nozzle. The atomizing nozzle comprises an air channel for establishing an air flow through the nozzle. The air flow is mixed with the flow of liquid aerosol-forming substrate to enhance atomization of the flow of liquid aerosol-forming substrate delivered through the atomizing nozzle.
