Numerical Simulation Of Indoor Tall And Big Space Contaminant Distribution

The application CFD software Fluent in this paper simulate flow and temperature fields for indoor, contaminant density field. Now building more and more develops to tall and big, complex geometry appearance, the design method of air of current tradition is not applying to tall and big space. For tall and big space, the major means are numerical and model experiments.Numerical simulation can consider various boundary conditions fast, disturb or outside disturb ,and respond all-sidedly the organization condition of air current. So how to be facilitated with numerical method, carry out numerical simulation fast efficiently for tall and big space become the problem that people pay attention to. This paper adopt porous material thermal source and quality source with effective easier method simulate the influence of crowd for indoor air quality and contaminant density, and set boundary and initial conditions reasonably to get the detailed conditions of indoor air current and CO2 distribution of contaminant density.
