CFD Modelling

FDS Consult uses the very latest fire modelling methods to predict fire conditions within a known space for a specific fire scenario.

Fire modelling studies are a vital element of our consultancy services, providing key information that allows us to design precise fire strategies. Without these detailed studies, many of our pioneering fire engineered solutions would not have been possible.

The main parameters we establish through fire modelling are:
• gas temperatures
• radiation fluxes
• toxicity levels
• combustion product yields and composition
• gas layer height
• and visibility levels

Two distinct types of fire modelling software programs are used to gather this information - zone modelling and field modelling - depending on the requirements of the project.

Zone Modelling
The quicker of two methods, zone modelling requires comparatively low amounts of initial information to setup the fire scenario. This can often be completed within a matter of just minutes. However, zone modelling only provides an overview of the likely outcome and can lack in-depth information on internal flows and gas compositions.

Field Modelling (CFD)
Field models, otherwise known as Computational Flow Dynamics (CFD), provide much greater detail on the behaviour of fluids in a given fire scenario. More complex and time consuming than zone modelling, field models demand larger amounts of detailed initial information.

FDS Consult tends to utilise CFD modelling studies on up to 90% of all consultancy projects, forming a key part of the design and validation process.
