Computational Fluid Dynamics
Smoke ventilation systems are commonplace in and crucial to fire safety design, and are often employed in buildings which are designed without meeting relevant fire safety standards. As a result, their use must be validated using a highly technical and engineered approach in order to prove suitable levels of safety in the event of fire.
CFD modelling allows an experienced engineer to simulate a fire of any size, composition and duration in buildings ranging from large warehouses to dead-end corridors in apartment blocks. Not only can CFD modelling demonstrate that smoke ventilation systems are suitable for a given scenario, but they can also help reduce the cost of such a system thanks to the accuracy of the analysis.
Trenton Fire has extensive CFD modelling experience over a large number and variety of projects. One of our senior engineers undertook a PhD in CFD modelling and his knowledge has contributed to several other engineers becoming proficient in this field. Our cumulative experience has allowed us to become efficient in the way we vary model parameters, streamlining the process to deliver a full solution in a cost-effective manner.
CFD modelling of a single stair apartment block with extended common corridor travel distances. The image shows the apartment of fire origin with a mechanical smoke extract system in the corridor preventing smoke travelling down the corridor and into the stair. The colours represent temperatures at head height (blue=cool, red=hot).
