Investigating cross-wind stability of high-speed trains with large-scale parallel CFD

Publikováno v: International Journal of Computational Fluid Dynamics. 30:402-407

The side-wind loading on a simplified train model at scale 1:25 is investigated by parallel large eddy simulation LES with incompressible solvers from the OpenFOAM package and a novel dynamically adaptive, parallel LES-type lattice Boltzmann method L

lnvestigating Side-Wind Stability of High Speed Trains Using High Resolution Large Eddy Simulation and Hybrid Models

Autor: Moritz Fragner, Ralf Deiterding

Publikováno v: Computational Methods and Models for Transport ISBN: 9783319544892

Crosswind flow over high speed trains can pose serious safety concerns for rail transport. Methodologies for evaluating the aerodynamic forces exerted on the train include full-scale measurements, physical modeling using wind-tunnel experiments and n

Comparison of industrial and scientific CFD approaches for predicting cross wind stability of the NGT2 model train geometry

Autor: Uwe Fey, Moritz Fragner, Keith Weinman, Ralf Deiterding, Claus Wagner

Safety assessments of cross-wind influence on high-speed train operation require a detailed investigation of the aerodynamic forces acting on a vehicle. European norm 14067-6 permits the derivation of required integral force and moment coefficients b
