Eulerian models are used to represent the air traffic environment as traffic flows between interconnected control volumes representing the airspace system. While these models can be manually derived for simple air traffic patterns, computer-based approaches are essential for modeling realistic airspaces involving multiple traffic streams. A computeraided methodology for deriving large-dimension...

When a liquid slams into solid, the intermediate gas is squeezed out at speed that diverges when approaching moment of impact. Although there mounting experimental evidence instabilities form on interface during such an event, understanding nature these limited. This study therefore addresses stability liquid-gas with surface tension, subject to diverging flow in phase, where and phase are both...

For the assessment of debris flow risk, it is essential to consider not only triggering and propagation stages but also perform analyses its effects consequences. The study aims at developing a procedure based on quantitative risk assessments able estimate different levels with reference transport linear infrastructures. This includes numerical modelling for flows determine zones where elements...
