Abstract: The three-dimensional (3D) model of cigarette was accurately constructed through reverse engineering as the research object of numerical simulation. The combustion process of cigarette was studied with computational fluid dynamics (CFD). Standard Laminar models with species transport approach were applied, and numerical simulation of the cigarette was analyzed with semi-implicit method for pressure-velocity coupling. The results showed that the model could predict velocity of cigarette smoke, the distributions of temperature and pressure at different times. In order to verify the correctness of model, it was found that the relationship between the velocity of smoke and pressure according to Darcy's law on z position (x=4 mm, y=0, 0 mm ≤ z ≤ 50.61 mm).
