Aerodynamics and Ventilation of Vehicle Tunnels
11th International Symposium on Aerodynamics and Ventilation of Vehicle Tunnels
Date: July 7, 2003 - July 8, 2003
Location: KKL Congress Centre, Luzern, Switzerland
Web Page: http://www.bhrgroup.co.uk/confsite/av03home.htm

Deadlines: April 7, 2003 (registration)
Type of Event: Conference, International
 
Description:

Road tunnels
  • Systems design issues (e.g. comparison of ventilation systems, control/monitoring strategies, choice of automated or procedural control, traffic monitoring and control, portal emission)
  • Road vehicles (emissions levels and future trends, traffic flow control, fire and smoke loads)
  • Practical design solutions Papers in this section are expected to focus on a closely defined topic and clearly demonstrate a novel approach or application. Areas could include: equipment; installations; passenger/use facilities.
Railway tunnels
  • System design issues (e.g. high speed transits, comparison of ventilation systems, control/monitoring strategies, choice of automated or procedural control, piston effects and loads on equipment, transient pressure alleviation, railway tunnel environment, thermal effects and humidity)
  • Railway vehicles (e.g. train construction, pressure sealing/air leakage, fire and smoke resistance, geometric profile, fire and smoke load, prediction of fire development, TSIs, design criteria for and maintenance of in-car conditions)
  • Practical design solutions Papers in this section are expected to focus on a closely defined topic and clearly demonstrate a novel approach or application. Topics may include pressure relief, noise mitigation, aeroacoustic ducting, micro-pressure wave mitigation, ventilated escape routes.
Practical and management issues (e.g. maintenance of ventilation systems, upgrading existing systems, air leakage between tunnels, systems specification, system testing)

Analytic techniques and validation (these papers should have a rigorous basis and validation. Topics could include flow and pressure effects in complex systems, vehicle/flow interactions, 1D, 2D or 3D simulations, interactions of multiple jets)

Discussing Key Issues

In addition to a technical programme of refereed papers, a feature of the 2003 Symposium will be an open session to raise and discuss key questions and future developments. Suggested areas for discussion include:

Automation of control 
Advantages of twin tube systems 
Smoke control strategies 
Overhead extraction 
Basis for comfort criteria 
Improved compressible modelling 
Improved thermodynamic modelling 
Confidence in CFD modelling 
Vehicle exhaust pollution - human effects, advancing 
knowledge, changing criteria, environmental health issues
