Abstract
A smoking substitute apparatus for generating an aerosol, comprising: a housing; an air inlet and an outlet formed at the housing; a passage extending between the air inlet and outlet, air flowing in use along the passage for inhalation by a user drawing on the apparatus; and an aerosol generation chamber containing an aerosol generator being operable to generate an aerosol from an aerosol precursor; wherein the aerosol generator is in fluid communication with a downstream portion of the passage for allowing the aerosol to entrain into an air flow along the passage; wherein the downstream portion of the passage comprises a flow converging section having a curved sidewall tapered towards the outlet, and wherein an upstream end of the flow converging section substantially conforms to a cross sectional profile of the aerosol generation chamber.
