Optimal Design Operation Strategies of a Hyperloop Transportation System

Denis Tudor

In the last decades, transportation demand growth has played a major role in the increase of global CO2 footprint. At the same time, a number of countries have scheduled measurable and substantial cutback of CO2 emissions by 2050. As the transportation sec ...

Climate-Neutral Global Aviation - are we on the right track?

Sascha Nick

Is climate-neutral aviation even possible, what would it look like, and how do we get there? It is difficult to imagine effective international climate action without making aviation climate-neutral, due to its significant and growing climate impact, and t ...

Effect of deflector aerator on stepped spillway flow

Anton Schleiss, Michael Pfister, Stéphane Christian Olivier Terrier

Systematic physical model tests are performed on a stepped spillway equipped with a bottom aerator at the beginning of the stepped part. A deflector is used to issue a jet in order to initiate air entrainment into the flow. A horizontal slot located in the ...

Comparison of chute aerator effect on stepped and smooth spillways

Anton Schleiss, Michael Pfister, Stéphane Christian Olivier Terrier

Bottom chute aerators are installed to prevent cavitation damages and they have been studied in detail on smooth spillways. In parallel, stepped spillways became widespread in the past decades. Research has shown that stepped spillways may be endangered ev ...
