Lava effusion in mountainous terrain generates flow backup and excess inundation [PDF]
Communications Earth & EnvironmentMost volcanic eruptions occur in high-relief terrains, however the impact of mountainous topography on lava emplacement is poorly constrained. Here we use analogue materials (syrup, glycerol) to investigate lava effusion where changes in channel width ...

Numerical Simulation of a Supersonic Ejector for Vacuum Generation with Explicit and Implicit Solver in Openfoam [PDF]
Energies, 2019 Supersonic ejectors are used extensively in all kind of applications: compression of refrigerants in cooling systems, pumping of volatile fluids or in vacuum generation. In vacuum generation, also known as zero-secondary flow, the ejector has a transient

Modernization of Todini Global Gradient Algorithm for hydraulic analysis of networks with choked flow [PDF]
E3S Web of Conferences, 2020 The modification of well-known Global Gradient Algorithm for hydraulic network flow distribution problem is proposed. This modification is based on problem equations rewritten in “upstream” form and on modified form of linearization, and can be ...

International Journal of Turbomachinery, Propulsion and Power, 2021 A mean-line compressor performance calculation method is presented that covers the entire operating range, including the choked region of the map. It can be directly integrated into overall engine performance models, as it is developed in the same ...
