FLASHOVER FIRE MODELLING BY REAL SMALL-SCALE MODELS

Modelling of fires as an important part of prevention of natural disasters is an essential part of research. Implementation of large scale test in fire prevention is extremely difficult and costly. The proper application of chosen method of large scale models can bring approximately the same results as with real objects. Fire experiments were done in completed 3D structure model according the fire scenarios. The obtained data is processed and analyzed with a focus on achieving the goals and tasks of individual solutions. When creating a representative model we will be based on the Froude modelling, reducing the time equation, energy equation, the border area and the fuel source through dimensionless groups. Monitors the temperature changes depending on the time of flashover at a speed of burning fuel to form a flashover, heat flux at ground level to form a flashover. Evaluation of the experiment perform the calculations of measured data through relationships in real time, reducing fire. The paper presents a fire experiment realised in a model with cubic dimensions stored inside the timber bearers representing wooden furniture in the room.
