Computational Fluid Dynamics (CFD) Analysis of Smoke Exhaust Systems

Under the fire scenario, effective evacuation of smoke from indoor spaces is crucial for providing a tenable environment to occupants without obscuring the signage and rescue paths. The design and operation of the smoke exhaust system play a vital role in determining the tenability. Ideally, the smoke should travel from the location of the fire to the exhaust in a “single-pass” flow path without obscuring the rescue route of occupants.

Several factors can affect smoke dilution and visibility. These factors include the size and location of the fire, exhaust fan capacity, placement of exhaust grilles, locations and number of makeup air openings, and space height and layout.

Our proprietary CFD analysis procedures help our clients to optimize the performance of the atrium smoke exhaust system as well as stairwell and elevator shaft pressurization. Our analyses predict smoke temperature, the concentration of toxic gases, and visibility.
