Smoke analysis for tunnels is a critical component of tunnel safety design. CFD simulations ensure effective ventilation systems to manage smoke distribution, visibility, and temperature in the event of tunnel fires.
Kolkata, India
The scope of work is to design the Smoke analysis for tunnels/Smoke distribution in inclined tunnel fire ventilation modes for tunnel ventilation system for the Underground Metro stations and to evaluate the performance of the design using CFD Modelling. Various Fire /tunnel fire scenarios were conducted.
A comparative smoke analysis for tunnels or smoke analysis for Metro was done using various design standards like Eurocode EN50126, NFPA 130, SIA, etc., to arrive at the most suitable standard applicable to Kolkata conditions. An experimental study was also conducted to assess the emergency ventilation mode, emergency management, and emergency mode. The local building code NBC was studied. NFPA 130 standard was largely used as a design guideline for the fire safety design of subway stations. A numerical study was also conducted to evaluate tunnel ventilation safety systems and assess the smoke movement/smoke layer.
