DES of the Flow Around a High Speed Train under the Influence of Wind Gusts
Paper i proceeding, 2008
Detached eddy simulation of flow around a highspeed
train exiting a tunnel and passing through a region
of varying crosswind is presented. Results using
two crosswind profiles with different velocity amplitudes
during and after the train’s passage are compared.
The flow surrounding the train after the passage
through the varying crosswind velocity profile
was found to return to a flow similar to that before
the exit from the tunnel in case when the final crosswind
velocity is zero. Thus the flow seems to forget
the passage through the wind gust.
