The 21st International Symposium on Aerodynamics, Ventilation and Fire in Tunnels is coming to Melbourne Convention and Exhibition Centre, Australia – 30th November – 2nd December 2026
What is ISAVFT?
The International Symposium on Aerodynamics, Ventilation and Fire in Tunnels (ISAVFT) is the world’s longest‑running and most authoritative conference series dedicated exclusively to tunnel aerodynamics, ventilation, fire safety, and underground environmental control. For over 50 years, ISAVFT has been the forum where the hardest tunnel safety problems are debated, tested, and advanced.
Deep Technical Focus
ISAVFT is unapologetically technical and rigorously applied. Core themes include:
- Tunnel aerodynamics (pressure waves, piston effect, comfort, high‑speed rail) Ventilation systems (longitudinal, transverse, jet fans, energy optimisation)
- Fire and smoke dynamics (critical velocity, evacuation, suppression systems) Air quality & pollution control
- Operations, maintenance & real‑incident lessons
- Advanced modelling (CFD, digital twins, full‑scale testing)
- Future transport (electric & hydrogen vehicles, automation, ultra‑high‑speed systems)
Academic Rigor, Industry Relevance
- Full peer review of all technical papers
- Keynotes from global leaders in tunnel safety and fluid mechanics
- Strong mix of research, design guidance, case studies, and failure analysis
- Trusted by those who design, approve, operate, and insure tunnels
ISAVFT bridges academia and real‑world consequence.
Global Pedigree
First symposium held in Canterbury, UK (1973), rooted in British hydromechanics research, ISAVFT is held every 2–3 years across Europe, USA, Australia, and beyond. Recent editions hosted in Lyon, Athens, Copenhagen, Melbourne, and other global centres. Organised under the ISAVFT / BHR lineage, maintaining continuity with its original scientific foundations.
The Bottom Line
ISAVFT is the global benchmark conference for tunnel aerodynamics, fire, and ventilation. Five decades. Peer‑reviewed. Incident‑driven. Open knowledge. Permanently citable.
When tunnels matter, ISAVFT leads.
The Sir Alan Muir Wood Prestige Lecture is a flagship, invited lecture held to honour Sir Alan Muir Wood, widely regarded as the father of modern tunnelling.
Sir Alan Muir Wood (1921–2009) was a pivotal figure in underground engineering: a leading consultant on the Channel Tunnel, founding President of the International Tunnelling Association (ITA‑AITES), former President of the Institution of Civil Engineers, and a driving force behind the modern, risk‑based approach to tunnelling design and delivery.
The lecture is reserved for internationally recognised thought leaders and provides a platform for:
Strategic reflection on tunnel engineering practice
Lessons from major projects and failures
Innovation, uncertainty management, and future direction of underground construction
It reflects Sir Alan’s central belief that engineering judgement, innovation, and understanding of risk—not prescriptive rules alone—are key to safe and economic tunnelling.
Within ISAVFT, the Sir Alan Muir Wood Prestige Lecture represents the highest‑profile intellectual contribution of the symposium, reinforcing ISAVFT’s role as a forum for:
- Long‑term thinking, not just technical detail
- Cross‑disciplinary insight across aerodynamics, ventilation, fire, and operations
- Knowledge transfer between generations of tunnel engineers
- The lecture is typically sponsored, formally presented, and positioned as a prestige event within the symposium programme.
Lectures are archived and published, forming part of the permanent technical record of the profession, consistent with Sir Alan Muir Wood’s commitment to open knowledge, professional leadership, and engineering excellence.
