AB - Standard bar of ventilation is the equipment extensively used in the tobacco  industry to calibrate the variety of testing machines. The bar’s performance  that is usually affected by ambient conditions is numerically studied in this  paper. Firstly, the geometry of standard bar is obtained by an optical  microscopic 3-D measurement. Then, Solidworks is used to build the 3-D model  of standard bar and Gambit is used to mesh the model. Finally, the  performance of standard bar under variant ambient conditions is analyzed by  Fluent. Compared with the experimental data, the numerical results are found  to be quite accurate, and it is found that the ventilation rate increases  linearly as temperature rise and decreases non-linearly with the growth of  pressure.
