Particle pollutant is the prime pollutant of most cities in china, the tiny particle accumulated lots of harmful substance, and it is the carrier of bacteria, revealing the Mechanism of particle transport has an important meaning on controlling the indoor particle pollutant and disease prevention. This article sets up the model of particle penetrating the building envelope based on mathematics modeling, this model takes the pressure difference between indoor and outdoor( air change rate in rooms), crack depth, crack height and particle size as the input parameters and using the CFD to do the simulation analysis , drawing a conclusion.
