Kurzfassung
The presentation contains the following items to analyze aerodynamic flow properties around the NGT2 train model in strong cross winds - Reynolds number 250k and 450k were considered, wind impact angles 0,10,20,30 degrees - A series of RANS calculations performed with OpenFOAM code - Comparison of wind tunnel data with numerical results in terms of aerodynamic coefficients, PIV slices and wall shear stress profiles - Cross verification simulation using the DLR TAU code - URANS and DDES calculations performed with OpenFOAM
