Sharing Space

To a large comprehensive convention center as an example, this paper analyses the flow characteristics of fire smoke of the main hall and the feasibility for sharing space as "Quasi safety zone". First, the fire scenario was identified through the fire hazard analysis, then, set a model and take a simulation analysis by fire simulation software FDS, based on this fire scenario which have been established. At last, draw conclusions according to the smoke flow properties.

Des Model

In order to investigate natural cross-ventilation in buildings, computational fluid dynamics (CFD) with the DES model is applied. The aim of this paper is to investigate the influence of surrounding buildings on natural ventilation in target building under different separation distances. The simulation results indicate that surrounding buildings has a significant impact on airflow structure and airflow rate of the target building. The flow characteristics in target building is determined by the flow regime in street canyon.

Fire Smoke

With the aim of evaluating capabilities of a ventilation system with jet fans to control fire smoke in an underground garage, we carried out a set of FDS simulation. According to the results, temperature and soot density of fire has reduced within an acceptable range. We believe that the ventilation system based on the jet fans has indeed controlled fire smoke effectively, thereby we have enough time for safety rescue.
