Abstract:
A nebulizer for entraining a liquid in a flow of a carrier gas from a carrier gas source at a select pressure, the nebulizer comprising:a nozzle defining a passage which is circular in cross-section and includes a converging section, a throat, and a uniformly diverging section all being coaxial and serially connected, the nozzle having an inlet at a mouth of the converging section and an outlet defining a primary orifice at a mouth of the diverging section, the inlet being connectable and in fluid communication with the carrier gas source at a select pressure;a reservoir for a non-aerosolized liquid to be entrained; anda conduit for conveying the non-aerosolized liquid in the reservoir between the reservoir and the primary orifice for aerosolization of the liquid by carrier gas exiting the primary orifice.
