Abstract The so-called Evacuated Tube Train (ETT) is currently being proposed as a
high-speed transportation system potentially competitive with airplane transportation.
Aerodynamic resistance is one of the most crucial factors for the successful design of an
ETT. In the present work, a three-dimensional concept ETT model has been elaborated.
The aerodynamic characteristics of the subsonic ETT have been numerically simulated
under different conditions. The train’s running speed varies from 600 km/h up to 1200
km/h, and the blockage ratio is in the range between 0.1 and 0.3. As the blocking ratio
and running speed increase, the resistance of the head car… More >
