A perforated planar member is spaced from the outlet of a vortex generating transducer and a tube is coupled between the outlet of the transducer and the perforated member to completely close the space therebetween. Preferably, the perforated member is a screen composed of non-conductive criss-crossing wires having resonant dimensions as to a component frequency of the sonic waves generated by the transducer. In addition, the screen is also preferably spaced from the outlet of the transducer a resonant distance as to the component frequency. A drag member is spaced from the perforated member. Preferably, the drag member is cylindrical and its axis lies transverse to the plane of the perforated member; the drag member is spaced from the perforated member a resonant distance as to a component frequency of the sonic waves generated by the transducer. Atomization in the described apparatus is enhanced by means of thermal and/or electrical energy.
