In this paper, A north floor heating bedroom in China has been chosen to set up the physical and mathematical models of indoor air flow. The 3-dimensional indoor air velocity and temperature distributions are numerical simulated with the k-ε equation and the SIMPLE algorithm. At the same time, using the particle trajectory model, taking the particles with 7.5μm, 3.5μm and 0.4μm diameters for instances, the mass concentration distribution of indoor particles leaked from windows has been simulated. And then the following conclusions can be gotten: The particles are apt to adhere to the air current; the concentration of particles with 7.5um diameter descends faster than the ones of 3.5μm and 0.4μm diameters in the direction of height; the particles Of 0.4μm diameter are influenced by thermophoretic and the Brownian Motion obviously, and the concentration is more homogeneous in the direction of height.
