| Abstract: | This study aims to explore the effectiveness of active window opening strategy in dynamic control of compartment fires in buildings of different scales, in order to optimize fire safety design and emergency response mechanisms. By constructing a numerical simulation framework based on the PyroSim fire model, fire behavior analysis was conducted under active window opening conditions for three typical partitioned areas. The dynamic evolution laws of key parameters such as temperature field distribution, smoke layer height, oxygen concentration, and heat release rate (HRR) were analyzed. The results indicate that the optimal strategy varies significantly with the size of the compartment. In small compartments, early horizontal ventilation effectively delayed flash ignition by reducing thermal feedback; Larger compartments benefit from segmented vertical openings to control smoke stratification and extend safe evacuation time. Medium sized rooms require a hybrid strategy to balance local suppression and system ventilation. |
