ABSTRACT
This research paper was conducted to study the smoke movement and ambient airflow in a
stairwell under free flow of smoke source in BN stairwell block building. The simulation
was carried out using Ansys CFD software in order to observe the behavior of smoke and
decide the best placement of ventilation at the BN stairwell block building. Ansys CFX
software is a computational fluid dynamic software for turbomachinery applications and
good to use for observing variety of fluid materials or even mixture of materials can be
done using CFX. The result was presented using contour figure for temperature, velocity
and density, while streamline of velocity and density was shown in order to know the flow
of the smoke itself. The graph for temperature, velocity and density was plotted and
analyzed in the result and analysis section. As the smoke propagated upwards from smoke
source at floor 1 depends on turbulent mixing in the stairwell in the current work, it was
then accumulated at floor 3 of the building thus would be a good placement for the
ventilation when simulating at floor 1.
