ASHEE
14 Aug 2015 | Contributor(s): Matteo Cerminara, Tomaso Esposti Ongaro
A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

bent: A model of plumes in crossflow
11 Nov 2010 | Contributor(s): Marcus I Bursik
Bent is an integral trajectory model for calculation of plume parameters in the presence of a crossflow (wind). It has been validated against data for eruptions from Kliuchevskoi and Avachinskiy volcanoes, Russia.

Confort 15 (Conflow improvement)
22 Apr 2016 | Contributor(s): Silvia Campagnola, Claudia Romano, Larry G Mastin, Alessandro Vona
We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...

Direct sampling of volcanic clouds
08 Feb 2011 | Contributor(s): William I Rose
Volcanic clouds have only sporadically been directly sampled. Sampling is advantageous to validate remote sensing. Direct sampling was more common in the 1978-1984 period before the hazards to jet aircraft were understood and when piston aircraft sampling was more prevalent. This sampling...

Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Contributor(s): Greg A Valentine
Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...
