Expert in Fluid Dynamics and Thermodynamics
Specialization in Tunnel Ventilation and Tunnel AerodynamicsDr. Alexander Rudolf was first exposed to tunnel ventilation and train aerodynamics in 1994 as a scientific assistant at the EPFL. He developed the simulation tool NUMSTA(R) as his PhD topic for Swissmetro (a predecessor of today's Hyperloop), which allows to calculate the aerodynamics of trains in a partial vacuum.
Since then he has remained loyal to the topic of ventilation and aerodynamics of railway, metro and road tunnels and has been able to contribute to first-class projects worldwide.

The ventilation of rail and subway tunnels has become one of the focal points in any tunnel project. Several accidents have rendered regulations stricter.
In road tunnel projects, beginning in the year 2000 the focus has shifted from fresh air supply to control of smoke propagation in an emergency.
While ensuring a high safety level and system availability, there is always substantial pressure to reduce costs during all phases of the project, i.e. the planning, the realization and the operation.
With the introduction of electric vehicles, the requirements for tunnel ventilation, especially when dealing with fires, will once again change significantly.
It all started with the computer programm NUMSTA (R) developed for the Swissmetro project (similar to what is now Hyperloop). It allows to simulate the wave propagation in road and rail tunnels and thus to obtain the time dependent flow values in such systems.
The simulation programm has been developed continously.
Now, it can be used to answer very specific questions about the flow propagation in complex tunnel systems including compressible effects, thermal effects, vehicles and fans.
Expert Services can be delivered for public and private clients, such as construction companies.
We can deliver officially appointed appraisals in tunnel ventilation and tunnel aerodynamic projects.
We can also deliver appraisals for projects involving similar subjects, such as HVAC and energy.
