One Approach to Experimental and Numerical Investigation of Longitudinally Ventilated Road Tunnels

Experimental installation as well as experimental and numerical investigations of the road tunnel ventilation are presented. Since recently, two modern single tube two-way traffic road tunnels, 4.2 km and 1.4 km long, are in use in Montenegro. In order to analyse the flow of the first one in detail, a smaller scale model corresponding to a 400m length of the real structure, has been constructed in the Laboratory of Faculty of Mechanical Engineering in Podgorica, Montenegro. It is equipped with a similar in geometry and function, scaled, ventilation system based on aircraft-modeling jet-fans powered by electric motors. The main tunnel tube is ventilated longitudinally, while the secondary (smaller evacuation tunnel) could be over-pressured with respect to the main tunnel, in the case of a hypothetic accident situation. Cross passages connect the two tunnels. The ventilation efficiency, pressure drop, and transient regime under changing air directions are experimentally and numerically investigated. The obtained experimental and numerical results are compared.
