Whatever the scale or nature of the project, let FDS Consult UK conduct a free fire safety assessment to maximise your design options and avoid non-compliance in key areas.
At FDS Consult UK, we know that our innovative approach works but we also know that we need to prove it. That’s where the computer (CFD modelling) comes in.
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 our fire strategy would work in practice.
Meanwhile, Evacuation Modelling and Time Equivalence Modelling ensure that we can prove that our evacuation strategies work and our use of Finite-Time Analysis can provide the evidence needed to help prevent the over-specification of fire safety measures.
Smoke Modelling
We have the most advanced technology at our fingertips because we’re at the vanguard of what we do and you can rely on our fire engineering consultancy to use these tools to help us secure fire approval for your building. FDS Consult UK provides CFD modelling that facilitates the building regulations approvals.
In this Q&A, Bijan Fard explains the valuable role Computational Fluid Dynamics modelling plays in fire safety, and what it means for the industry.
CFD Modelling
Q. What is Computational Fluid Dynamics modelling?
A. 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 many industries such as aerospace and automotive design.
Q. How does FDS Consult UK use it?
A. In fire engineering terms, the CFD modelling software maps the spread of fire and smoke through a detailed virtual representation of the building in question.
This can be created from building plans allowing design decisions to be made at an early stage of the project.
Q. How does CFD modelling help you to plan fire safety in buildings?
A. It is possible to simulate the fluid dynamics (movement) of the smoke and fire over a set time period allowing its physical behaviours, for example – smoke rising, to be observed as it unfolds. It shows us how the proposed layout and features of the building will affect the spread of the smoke, enabling us to create an informed fire safety strategy and demonstrate how it will work in practice. The computer model also highlights any areas of concern, such as where smoke is hotter or denser, or where fire may spread more quickly.
Q. What is CFD modelling’s role within the design process?
A. During the planning stages, the model is used to pinpoint areas that are susceptible to the build-up of smoke. This in turn tells our designers and fire engineers where to allocate the necessary safety systems such as smoke ventilation, pressurisation systems and sprinklers.
Once the safety systems have been incorporated into the virtual model, the simulation is rerun to show how effective the various fire safety systems will be in their designated positions. This allows for any areas of development or improvement to be spotted and implemented.
Q. Why is it important to consider fire safety during the early stages of a project?
A. Creating a bespoke fire strategy at the beginning of each building project ensures that the safety requirements can be met. Making changes during the design phase in response to the results of analysis is far less costly than making adjustments once the build is progress.
Furthermore, CFD Modelling actually encourages greater design freedom for architects whilst also providing more saleable space. The superior level of accuracy and detail that CFD Modelling provides allows smoke ventilation and fire suppression systems to be optimised. This means 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.
Q. In your opinion, to what extent can the use of computer software enhance the industry’s future in fire design?
A. The use of computer software has made way for a more creative, thorough and tailored approach to fire design. This is further supported with the introduction of additional software such as Evacuation Modelling, Time Equivalence Modelling and Finite-Time Analysis – systems that help us prove our evacuation strategies work as they should, as well as provide the necessary evidence of the efficiency of fire safety measures.
