Position of a ppv fan when ventilating the stairwell Evaluation Using CFD Modeling The performance of positive pressure system would be difficult to evaluate via testing under live fire conditions in a high-rise building.
Fig.2 Model domain for 10-story stairwell with fire compartment adjacent to the 3rd floor of the stair Critical Velocity and Fan Velocity in Simulation Fig.3 Smoke backflow with high air velocity through an open doorway Thomas determined that airflow in a corridor in which there is a fire can almost totally prevent smoke from flowing upstream of the fire [5].
A relatively large air velocity of 5 m/s is set in FDS simulation according to Table 1.
The simulations performed using FDS showed that PPV has the potential of providing equivalent protection to a typical stair pressurization system, without the associated problems due to door overpressure exacerbated by stack effect.

A simulation model is developed to predict removal rates by MATLAB/Simulink.
