ABSTRACT:
An improved atomization system for aerosolizing liquids including a vortexing nozzle and a flat or protruding face on the nozzle exit orifice. The system can also include a diverging mouthpiece insert. The present invention can produce a high fine particle fraction and modest throat deposition in conjunction with reduced aerosol plume velocity and impact force.
