Vacuum Transport Seminar Session 6 | 31.05.2021 at 18:00 CET

One of the main advantages of the hyperloop is that it can reach faster speeds easier than conventional means due to its higher efficiency. This talk aims to answer the questions about the energy-saving capability of the hyperloop. The literature is investigated for studies simulating the effects of drag, the energy saved is calculated, and the results discussed. Using this data, the question “Is the energy saved enough to power the vacuum pumps?” will be answered.

The field of tunnel fluid dynamics has been thoroughly researched since the second half of the 20th century due to the rapid development of high-speed railway transportation. The flow generated by a high-speed vehicle crossing a tunnel is significantly different from that observed in the open air. Its unsteady, turbulent, and compressible behavior usually requires using numerical methods for its analysis. The investigation of ultra-high-speed ground transportation (UHSGT) bodies moving through an enclosed environment is particularly complex due to the higher flow velocities and the blockage ratios in comparison with high-speed railway aerodynamics. This talk reviews the most relevant CFD techniques that allow a correct simulation of the flow phenomena of UHSGT bodies moving through closed tubes.
