Simulation of Fire Development
Analyses of fire development can make it possible to achieve more flexible fire protection solutions. Depending on the complexity of a building, simple or advanced methods are used for fire modelling. For large or complex buildings, 3-dimensional CFD (Computer Fluid Dynamics) models can be applied to determine fire conditions, such as smoke temperature, visibility and toxicity.
Examples of appropriate areas of use of CFD:
- Development of larger and more open general layouts than allowed according to prescribed national building regulations.
- To study spread of smoke in complex buildings.
- Design and optimisation of smoke ventilation.
- Finding alternative evacuation strategies for buildings.
- Determine non flash-over conditions in certain buildings to permit alternative design solutions for load bearing structures.
- The method is particularly suitable for large buildings with high ceilings.
Using complex models, all fire protection requirements of the society can be fulfilled, while solutions can become more flexible and in some cases even significantly cheaper.
