Abstract
An apparatus for generating aerosol comprises a capillary tube comprising at least one bend, fluid inlets, regions of reduced wall thickness located between the fluid inlets and the at least one bend, and an outlet along the at least one bend. The capillary tube is heated to a temperature sufficient to volatilize fluid in the capillary tube, such that the volatilized fluid discharges from the outlet to form an aerosol.

An aerosol generator in the form of a capillary tube, the capillary tube comprising at least one bend, fluid inlets, regions of reduced wall thickness located between the fluid inlets and the bend, and an outlet along the bend, wherein volatilized fluid discharges from the outlet to form an aerosol.
An aerosol generator comprising:
- a capillary tube comprising at least one bend, fluid inlets, regions of reduced wall thickness located between the fluid inlets and the bend, and an outlet along the bend;
- and
- a heating mechanism which heats the capillary tube to a temperature sufficient to volatilize fluid in the capillary tube.
A method for generating an aerosol, comprising the steps of:
- supplying fluid to an aerosol generator comprising a capillary comprising at least one bend, first and second fluid inlets, regions of reduced wall thickness located between the fluid inlets and the bend, and an outlet along the bend;
- and
- heating the capillary to heat the fluid to a temperature sufficient to volatilize the fluid to form a volatilized fluid, such that the volatilized fluid discharges from the outlet of the capillary to form an aerosol.
