    The use of nonlinear constitutive equations to evaluate draw resistance and filter ventilation

    EITZINGER B.; EDERER C.
    WFT Research, Trierenberg Holding, Traun, Austria
    This study investigates by nonlinear constitutive equations the influence of tipping paper, cigarette paper, filter, and tobacco rod on the degree of filter ventilation and draw resistance. Starting from the laws of conservation, the path to the theory of ...

    A review of the incidence and consequences of cigarette filter vent blocking among smokers

    BAKER R.R.; LEWIS L.L.
    British American Tobacco, R&D Centre, Southampton, UK
    Vent blocking, the covering of the filter ventilation zone on a cigarette during smoking, is a potentially important aspect of smoking behavior. Various techniques have been used to assess the incidence of vent blocking, and widely different views have ...

    Alternative smoking regimes: - techniques for predicting mainstream yields with varying degrees of cigarette filter vent blocking

    CASE P.D.
    British American Tobacco, Group R&D, Southampton, UK
    The cigarette industry is currently being asked by various regulatory bodies to provide significant quantities of supplementary data on tobacco products. Included within some of these requests is a requirement for mainstream smoke yield data under a ...
