Overview

This event offers invaluable insights into improving road tunnel ventilation systems.

Hear first-hand from experts who collaborated with Australian road tunnel operators to enhance their ventilation using advanced simulation tools. Learn how Ventsim DESIGN, a 1D network flow simulation tool with a 3D graphical user interface, was adapted for tunnel-specific challenges like jet fan pressure and vehicle piston effects.

Discover the detailed process of building validated models, calibrated with real-time sensor data, and how these models were used to trial and implement successful changes. Key topics include reducing power consumption, optimising fan use and modifying emission requirements.

By attending, you’ll gain practical knowledge applicable to tunnel ventilation and other engineering challenges, witnessing the real-world impact of these innovations. Don’t miss this opportunity to network with industry professionals and stay ahead with cutting-edge ventilation solutions.

Learning outcomes

In this presentation, you will learn about:

• The approach taken in modelling ventilation in operational road tunnels, informed by experience in underground mine ventilation and model calibration.
• Various approaches taken in mining and how they may or may not be applicable to tunnel ventilation.
