| Abstract: | Nowadays, simulation has become one of the basic methods of research in the modern fire science. Using computing simulation software to simulate a fire development of a large open plan is one of the frontier topics in fire dynamics research. Fire behaviours in a large open plan are entirely different from a classic small compartment fire, which cannot be simply described by standard fire. Large open plan fire is a challenging area to study since there are some unknown factors to be considered. People are still working on it. This study focuses on the fire spread rate under different conditions. Revit, PyroSim and Fire Dynamics Simulator (FDS) are used in this study. This study compares the fire spread rate of five simulation schemes including one homogenous fuel scheme, two non-homogenous fuel schemes and two ventilation schemes. For all the simulation schemes, total fire load and burner remain constant. It mainly studies the influence of ventilation conditions and different spacing of lump fuels on fire spread rate. BIM (Revit) is used to build the model firstly, and then PyroSim and Fire Dynamics Simulator (FDS) are used to simulate the fire behaviours in different fire schemes. Finally, the fire spread rate is calculated with the output data from the software. Based on the above simulation schemes and calculated results, it is found that the fire spread speed is significantly affected by the spacing of lump fuels and ventilation conditions. For non-homogenous fuel schemes, fire spread rate decreases with increase of the spacing of the lump fuels. For ventilation schemes, fire spread rate is much faster in fewer windows schemes than that in more windows schemes. Therefore, it is recommended to add as many windows as possible and reduce the spacing of lump fuels in the large open plan office fire design. |
