TEKIA and tunnel ventilationAt TEKIA, our experience in different urban and high-speed railways allows us to offer safety engineering solutions that cover everything, from designing the system to defining operations and emergency procedures.
During the commissioning of a tunnel, and also regularly during its use, the ventilation system should be audited. TEKIA uses a contrast methodology to assess the tunnel ventilation and evacuation system design based on 3D simulation and on-site tests carried out with our own equipment.
At TEKIA, we have been involved in over 100 tunnel ventilation projects, both road and railway, all over the world.
Tunnel ventilation at underground infraestructures
Sizing ventilation systems in tunnels.
Defining the operation of ventilation systems (algorithms)
CFD (Computational Fluid Dynamics) studies simulating fire scenarios and its evolution.
Pedestrian egress studies in case of emergency both in tunnels and train stations, using CFD simulations results as an input.
Evaluation of the operation of ventilation systems with aerodynamic and hot smoke tests.
Aerodynamic test: measurement of air flow velocity in different scenarios using ultrasonic anemometers.
Hot smoke test: fire drills by generating hot smoke with own-manufactured machinery.
