| Abstract: | The adoption of natural ventilation systems for smoke extraction in rock caverns offers an alternative to mechanical ventilation systems. This research investigates the feasibility and effectiveness of natural ventilation as a reliable solution for smoke management in rock caverns. Using computational fluid dynamics (CFD) modeling, various fire scenarios were simulated to analyze smoke propagation and the performance of natural ventilation systems. The research findings indicate that natural ventilation can effectively remove smoke and hot gases from rock caverns, maintaining lower temperatures and better visibility. The effectiveness of natural ventilation was found to be influenced by the size of vents and fire size. The research provides recommendations for optimizing smoke control strategies. This study demonstrates that natural ventilation systems are a practical and effective solution for smoke extraction in rock caverns. By optimizing vent design, natural ventilation can significantly enhance fire safety, ensuring effective smoke management and occupant safety in underground facilities. |
