Aerodynamic energy consumption analysis of divided evacuated tube transportation system

Aerodynamic energy consumption analysis of divided evacuated tube transportation system

Evacuated Tube Transportation (ETT) reduces aerodynamic drag and energy consumption by lowering gas pressure around high-speed trains (HSTs). To optimise this effect, integrating the ETT system into high-speed cruise segments is a practical approach, though it may introduce vacuum potential energy l...
