Applications of CFD Modelling in Fire Engineering
Our CFD fire simulations are used for:
✔ Mechanical Smoke Control System Design – Optimizing the effectiveness of smoke ventilation and extraction systems.
✔ Atria Smoke Clearance Analysis – Ensuring efficient smoke management in large open spaces. Delta Fire Engineering are experienced in delivering these within commercial settings.
✔ ASET vs. RSET Analysis (PD 7974-6) – Quantifying Available Safe Egress Time (ASET) in comparison to Required Safe Egress Time (RSET) to assess evacuation safety.
✔ Fire & Smoke Spread Modelling – Simulating fire growth, smoke movement, and thermal effects to assess risk and develop mitigation strategies.
✔ Validation of Fire Engineering Designs – Supporting performance-based fire safety solutions to demonstrate compliance with BS 7974, BS 9999, and Approved Document B.
✔ Fire Research & Innovation – Contributing to the advancement of CFD fire modelling techniques through ongoing research and development projects.

Delta Fire Engineering undertook CFD analysis on an existing and historic former government office building in Central London. The proposed scheme was undergoing major refurbishment as part of a change of use. The building consists of four basement levels and ground plus six storeys.
Delta Fire Engineering were appointed to undertake a Computational Fluid Dynamics (CFD) analysis to validate the proposed design solution with mechanical extract shafts.

Delta Fire Engineering were engaged to provide fire engineering support with respect to a residential development located in East London. The scheme was an existing residential building arranged over two blocks with a total of four cores each served by a single stair (two cores in each block). The building consists of four storeys (ground plus three) where the apartments are accessed directly from the single communal stairs. The proposed development aimed to provide an upward extension of one storey to each block which will contain of a total of six apartments. We outlined the input parameters and acceptance criteria for a Computational Fluid Dynamics (CFD) modelling in relation to the required size and optimal location of the Automatically Opening Vent (AOV) at the head of each stair.

CFD Peer Review
Delta Fire Engineering were engaged to carry out a peer review of the CFD smoke ventilation analysis report for a proposed development involving the refurbishment and extension of an existing 5 storey (ground +4 floors) office building, to create a ground plus 6 storey development, with extension to the rear of the existing building that will be above an under-croft car park in Central London.
Our detailed report provided commentary against each of the report sections describing our observations, opinions and expert recommendations.
