SIMULATION MODEL OF AIR MOVEMENT IN THE MULTI-ROOM BUILDINGFunded under: FP1-ENNONUC 3C
The subject of this report is air flow simulation in multi-room buildings, based on a "global" approach. Prediction of the natural ventilation air infiltration rate and air movement in multi-room buildings has been the subject of many theoretical and experimental investigations. Not only the thermal performance of the building, but also fire propagation and the transport of smoke and other pollutants, have been extensively studied in relation to these phenomena. The model presented here covers steady and unsteady air flow in buildings with a complex configuration. This model makes it possible to predict the air infiltration rate and flow paths in the whole building, depending on wind parameters (velocity, direction, air temperature) and inside conditions (closed/open door, window etc.). In the case of dynamic wind flow, the model uses a steady flow algorithm for generation of the pressure field around the building and covers the frequency of wind pulsations in the range 0.1 - 1 Hz. In this way it is possible to obtain the trajectories of all relevant air flow characteristics (pressure, mass air flow rate, temperature etc.) through time.
