Seminar 43 -- Design Considerations for Tunnel Ventilation Systems

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Tunnel ventilation system design presents unique and challenging problems. This seminar will present various engineering solutions adopted to solve the tunnel ventilation design problems. This seminar will present 1) analysis techniques to design a tunnel ventilation system to accommodate trains pulled by diesel locomotives in rail tunnels; 2) analysis using both CFD and 3D egress modelling for smoke ventilation in tunnels.
