🔥 15 MW Train Fire Simulation in Tunnel | With vs Without Jet Fans (FDS + Smokeview) 🔥

Описание: This video shows a 15 MW train fire simulation in a tunnel using the Fire Dynamics Simulator (FDS) with visualization in Smokeview.

The simulation results include:

Smoke spread and Heat Release Rate (HRR)

Soot visibility and optical density

Temperature distribution along the tunnel

Velocity profiles of hot gases and smoke

The video is presented in two parts:
🚫 First Half – Without Jet Fans: uncontrolled smoke movement, poor visibility, and higher temperatures.
✅ Second Half – With Jet Fans: effective smoke control, improved visibility, and enhanced evacuation safety.

This comparison demonstrates the critical role of jet fan tunnel ventilation systems in fire safety design, smoke management, and evacuation planning.
