    WFT Research, Traun, Austria; WFT Research, Wattens, Austria.
    It is well known from experimental evidence and theoretical considerations that the diffusion constant of cigarette paper is approximately proportional to the square root of the air permeability. Despite this fact one frequently sees the need to control ...

    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 ...
