Study on Braking Panels in High Speed Trains Using CFD
With speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. In this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. The results of simulations are carried out with the computational fluid dyna...
متن کاملEurostar e320 high-speed trains
In December 2010, Eurostar International Ltd. awarded Siemens a contract for ten interoperable 16-car highspeed trains. These trains are based on Velaro®, the world’s most highly diversified high-speed platform.
