Ventilation of railway tunnels
The ventilation design of a metro or railway tunnel system requires broad know-how in various fields: from profound knowledge in aero- and thermodynamics and the capability to perform simulations of complex tunnel systems to the implementation of the design into operational, reliable ventilation systems.
