| Abstract | ||
| Hot smoke from fires poses a major threat to the safety of both building occupants and firefighters, with smoke inhalation responsible for around 85% of fire-related deaths. The extreme temperatures of smoke can cause serious burns to the skin and respiratory system, and extended exposure may lead to fatal injuries. To address this hazard, the present study conducts a thorough experimental and numerical analysis using Computational Fluid Dynamics (CFD) to enhance Smoke Management Systems (SMS) in enclosed spaces. The research specifically examines the role of Air Changes per Hour (ACH) in reducing smoke-related risks. Temperature trends over time were recorded for three different ACH levels. Findings highlight ACH as a critical factor influencing system performance in confined environments. Additionally, A CFD simulation was conducted for one of the test scenarios, and the results exhibited a comparable trend that closely matched the experimental data, supporting the CFD model's potential for broader applications in smoke control planning. | ||
