Abstract
A smoking substitute apparatus is disclosed, having: an air inlet; an outlet; and a flow passage formed therebetween. A vaporization chamber is in communication with the flow passage, the vaporization chamber having an aerosol generator configured to generate an aerosol from an aerosol precursor by heating. The aerosol generator comprises a vaporizer element loaded with aerosol precursor, the vaporizer element being heatable by a heater and presenting a vaporizer element surface to air in the vaporization chamber. A vaporizer element region is defined as a volume extending outwardly from the vaporizer element surface to a distance of 1 mm from the vaporizer element surface. The air inlet, flow passage, outlet and the vaporization chamber are configured so that, when the air flow rate inhaled by the user through the apparatus is 1.3 L min, the turbulence intensity in the vaporizer element region is not more than 1%.
