Ensuring fire safety and compliance with advanced CFD Analysis
At Navier Flow Consultants, we specialise in providing CFD analysis for residential apartments to ensure that smoke ventilation systems meet the expected standards of performance. Our work helps demonstrate that smoke ventilation is designed to provide effective smoke clearance and protect stairwells, ensuring safe evacuation and compliance with fire safety regulations.
Meeting critical smoke ventilation criteria
Means of Escape (MOE):
- Restore corridors and escape routes to tenable conditions (visibility > 10m and temperature < 60°C) within 2 minutes after evacuation.
- Ensure stairwells remain free of significant smoke for safe evacuation.
- Verify that pressure differences across doors do not exceed 50 Pa, allowing doors to be opened with ≤100N of force.
Firefighting (FF):
- Maintain stairwells free of significant smoke to facilitate firefighter access.
- Ensure tenable conditions in lobbies and stairwells for firefighting operations.
- Confirm that pressure differences across doors remain below 50 Pa, enabling ease of access during emergencies.

Why CFD analysis matters?
CFD analysis plays a crucial role in verifying the performance of smoke ventilation systems. It provides fire authorities, designers, and developers with evidence-based insights to demonstrate compliance with regulations and ensure occupant safety. Our advanced simulations model smoke movement and heat distribution, allowing us to assess and optimise ventilation systems under realistic fire scenarios.
Our approach to smoke ventilation CFD modelling
- Detailed Simulations: Using NISTS’s FDS code, we accurately model smoke dynamics to evaluate system performance in corridors, lobbies, and stairwells.
- Tenable Condition Validation: Our analysis focuses on maintaining visibility, temperature thresholds, and pressure balance in critical escape routes.
- Compliance Assurance: We align all assessments with the latest guidance from the Smoke Control Association (SCA) and relevant fire safety standards, such as BS 9991 and BS 9999.
