Abstract: In this study, fire growth and smoke propagation in enclosures are numerically modeled based on the material properties, ventilation and the enclosure geometry of similar geometries. Thing such as combustible materials, ventilation openings, and ceiling height affect the fire behavior. This research employs the Fire Dynamics Simulator (FDS) to study the influence of the ventilation conditions on the ceiling jet phenomenon, heat release rates (HRR) and smoke movement. Its high flammability is analyzed, as polyurethane foam is a key material in the development of fire. The results show that ventilation plays an important role in fire dynamics, depending on ceiling height, and highlight the weaknesses of existing numerical models regarding the smoke propagation in the situation of complex scenarios. Understanding fire behavior in mechanically ventilated spaces improves and insights into improving fire safety strategies in building design and emergency response.
