Abstract EN
Longitudinal ventilation systems are commonly installed in new tunnels.
In this paper, based on the similarity law, the scale model with a view to different conditions is carried out to study the effectiveness of twin-tunnel complementary ventilation system.
The system can offer enough amount of fresh air to meet requirement of driving safety by using longitudinal ventilation without ventilation shaft.
Field measurements were also performed to validate the numerical model.
Results reveal that particle concentration distribution is influenced by the distance from air interchange cross-passages to uphill tunnel inlet (Lex) and the flow volume of air interchange cross (Qex) passage and jet fan thrust (Pjet) in tunnel.
And Lex is the most important factor about influencing the ventilation efficiency.
