CFD and Evacuation Modelling

Fire Check Consultants have the wide experience and tools necessary to carry out detailed Computational Fluid Dynamics (CFD) simulations to determine the effects of fire and calculate the products of combustion within the built environment. The output of the work can be used to assess human tenable conditions, determine smoke control system requirements, model fire spread and received radiant heat, model fire detector and sprinkler activation times, and determine the effects of fire protection systems.

Our consultants can undertake three dimensional real time analysis of occupant evacuation during a fire condition. The modelling can be undertaken using a distribution of occupant characteristics including social behaviour, familiarity and movement speed. The results of the evacuation model can then be interlinked with the results of the CFD modelling to determine the tenability conditions in escape routes. The results of such analyses are very useful in determining fire safety system requirements and for demonstrating fire safety compliance with regulatory authorities.
