Sofie

The use of CFD models within fire research has undergone an explosive increase of new applications. In recent years, SP - Fire Technology has increased its expertise substantially to meet the growing demand from its customers. We can offer you quality work with short delivery times for specific, customer-based problems as well as for applied and fundamental research.

Large Data Base

A critical phase in CFD simulations is the definition of the fire growth. SP has one of the largest data-bases in Europe on full scale and small scale tests in this field, with long experience in full scale testing. Thus, we are well suited to provide expert guidance concerning the choice of fire source to be used in the CFD modelling.

Fire investigations 

Post-fire investigations are a growing field of application for CFD modelling. SP has experience from the simulation

Tunnels 

Recently a number of serious tunnel fires have occurred. The spread of smoke in these fires has hampered evacuation and fire suppression. Using CFD models, the complex ventilation situation inside tunnels can be studied. At SP we have world renowned experts in this field. In this capacity we have already assisted several recent tunnel projects, e.g., the Öresund link between Sweden and Denmark.

Chemical Species

The production and movement of toxic species in a complex fire is very important and difficult to model in detail. SP has conducted research into this area, concentrating specifically on the monitoring of the concentration of carbon monoxide (CO) in fire gases. Other toxic species are also important and the CFD model used in this work include hydrogen cyanide (HCN).

Flame Spread

When combining CFD models with numerical or empirical flame spread models the fire growth itself can be investigated. Further development is currently underway for a more sophisticated implementation. Practical examples with cable fires and room tests have already been performed.

Smoke and Fire spread

Smoke and fire spread in complex buildings such as atria can be predicted by means of CFD calculations. The increasing computer speed has made it possible to begin simulating more complex buildings with reasonable calculation times.
