Investigating cross-wind stability of high speed trains with large-scale parallel CFD
The side-wind loading on a simplified train model at scale 1:25 is investigated by parallel LES with incompressible solvers from the OpenFOAM package and a novel dynamically adaptive, parallel LES-type lattice Boltzmann method implemented in our own AMROC framework. It is found that the new LBM code provides more accurate time-averaged force predictions, while compute times are reduced.

Abstract

The side-wind loading on a simplified train model at scale 1:25 is investigated by parallel LES with incompressible solvers from the OpenFOAM package and a novel dynamically adaptive, parallel LES-type lattice Boltzmann method implemented in our own AMROC framework. It is found that the new LBM code provides more accurate time-averaged force predictions, while compute times are reduced.
