Simulation of a compartmentalized fire breaching its container under the impact of different heat release rates

Research on fires within a compartment is central to understanding building fires. Making use of the software fire dynamics simulator (FDS), a simulation of an ISO9705 standard room fire was conducted. First, different combustible materials were considered, and then the relationship between the surface area available to burn and the heat release rate was discussed. The result shows that the heat release rate per unit is impacted by the unit's placement in the room's grid, and the larger the surface area burning, the steadier the heat output. Temperature and velocity curves for the simulation and for Steckler's test were then compared. The result shows that the curves of the simulation comply with the curve of Steckler's test. Changes to the heat release rate were seen when the compartment was breached, as this affects characteristics of flow. The higher the designed heat release rate of the fire, the lower the height of the neutral plane at the opening.
