Study on the effects of air blowing on operation characteristics of high-speed trains with pantograph raised and lowered

To address the aerodynamic performance challenges caused by cavity flow in the pantograph area of high-speed trains, this study investigates a three-car train set using the improved delayed detached eddy simulation method based on the SST (Shear Stress Transport) k-ω turbulence model to systematically simulate acti...
