Aerosol-generating article with low resistance to draw and improved flavour delivery

Abstract

An aerosol-generating article extending from a mouth end to a distal end is provided, including: an aerosol-generating element; and a downstream section located downstream of the aerosol-generating element, the downstream section extending from a downstream end of the aerosol-generating element to the mouth end of the aerosol-generating article, a resistance to draw (RTD) of the downstream section being less than 10 mm H2O, between about 5 percent and about 35 percent of a length of the downstream section includes a first section defining a first empty region for air to flow, at least about 65 percent of the length of the downstream section further includes a second section defining a second empty region for air to flow, and a total cross-sectional area of the first empty region defined by the first section being less than a total cross-sectional area of the second empty region defined by the second section.
