WebbI have experience in aerodynamics calculations using the one-dimensional program ThermoTun, studying the effects of the pressure waves in high speed tunnels caused by the passage of trains through tunnel networks. I have studied approximately a total of 100 km of tunnel in preliminary design, during works construction and also during service … Webb5 juni 2013 · www.ThermoTun.com. Google Scholar. 24.
