CFD Fire Modelling and Advice

Photuris Fire offers a variety of innovative fire consultancy services, working with architects, designers, and approval authorities to create the optimized fire safety strategies. One of the tools we use is Computational Fluid Dynamics (CFD) fire modelling.

Computational Fluid Dynamics (CFD) modelling uses computer analysis to show how fluid or air moves over a surface or within a space and is used in a variety of industries including aerospace and automotive design. When applied to fire design, the CFD modelling software uses a detailed virtual representation of the building created from the plans to simulate and map the spread of fire and smoke. It shows how the proposed layout and features of the building will affect the spread of the smoke and highlights any areas of concern, such as where fire may spread more quickly or areas where smoke is hotter or denser.

This enables the creation of an informed strategy and once the safety systems have been incorporated into the virtual model, the simulation is run again to evaluate the effectiveness of the fire safety systems in their proposed positions and configurations. This allows any areas of development or improvement to be identified and implemented. Importantly CFD modelling can also be used to prove the effectiveness of a strategy and compliance with building regulations.

The superior level of accuracy and detail that CFD Modelling provides allows smoke ventilation and fire suppression systems to be optimised. This provides a greater degree of design freedom and there is often scope to expand room sizes and corridor lengths beyond what is suggested in the fire regulations by demonstrating that the safety of occupants is maintained. However, this is most effective if completed earlier in the project when changes can be made more easily. For this reason, it is important to involve fire safety specialists during the initial phases of the project.

Digital analysis and simulation techniques such as CFD modelling allows a more reliable and tailored approach to designing fire safety systems. This not only prevents costly additional work by ensuring compliance but also allows the building layout to be optimised.

Why use us for CFD Fire Modelling?

When a building burns often the smoke inhalation or heat transfer can be more hazardous than the movement of the flames, so it is important to assess how this may occur in the event of a fire. This can then influence means of escape planning and the design of passive and active fire systems.

By using the most advanced computer modelling techniques, we can present a clear and substantiated case for a more creative approach to fire design. Our use of Computational Fluid Dynamics Modelling (CFD Modelling, also known as Smoke Modelling) allows us to create a virtual replica of your building and map the spread of fire and smoke to demonstrate how your fire strategy would work in practice.
