Abstract Two flow cases for scaled high speed train models with different length
are numerically analyzed in the framework of the improved delayed detachededdy simulation model. Specific attention is paid to the shear flows and related
mechanisms in the near turbulent wake created by these moving models. In particular, a comparative analysis is made on the distributions of turbulent kinetic
energy (TKE) and turbulence production (TP) in planes perpendicular to the
streamwise direction. The numerical results suggest that, in the wake region very
close to the tail, significant TKE and TP can be ascribed to the dynamic interaction between powerful eddies… More >
