Regulation mechanism of underbody flow field and aerodynamic drag reduction for high-speed trains via mixed-gas jets
The bogie region is the primary source of aerodynamic resistance for high-speed trains, making it a key target for flow control strategies aimed at drag reduction. Numerical simulations were performed to explore the flow regulation mechanism and associated drag reduction effect of underbody mixed-gas jets with varying...
