It is important to predict the environment around the breathing human because inhalation of virus (avian influenza, human influenza, SARS) is recently severe worldwide problem. And air pollution caused by diesel emission particle (DEP) and asbestos attracts a great deal of attention, and their restrictions are becoming tight. In the present study, three-dimensional numerical simulation is carried out to predict the gas-particulate two-phase flows around breathing human and how suspended particulate matter (SPM, diameter ∼ 1 μm) reaches the human nose in inhalation and exhalation using Lagrange approach for particle motion and k-ε model for flows. Our research is a unique dealing with micro particle motions. Such small particles have great ability to affect our health in some case. In the calculation, the authors find out the smaller breathing angle and the closer distance between human nose and pollutant region are effective in the inhalation of SPM.
