Abstract
Results of large eddy simulation of the flow around a simplified train model moving through a crosswind are presented. These results are compared with the experimental data and show good agreement. The Reynolds number based on the inlet velocity and the height of the model is 22 615. In addition to the simulation of the flow around the moving model, another simulation was made of the flow around a stationary model influenced by the maximum crosswind from the moving case and the results are compared with the moving case. Overshoots were observed in several aerodynamic coefficients of the moving case over the stationary case. The yawing moment coefficient displayed an overshoot of some indicating the importance of performing the dynamic tests for the purpose of fulfilling safety standards.
