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...

PlumeMoM is a numerical code for the steady-state plume model, describing the rise in the atmosphere of a mixture of gas and volcanic ash during an eruption. The system of equation is formally the same of that presented in Barsotti et al. 2008, i.e. the equations we formulate describe the same...

Plates vs. Plumes Debate
07 Oct 2011 | | Contributor(s):: Gillian Rose Foulger
Early in the 21st century, scientists became increasingly skeptical about the deep-mantle plume hypothesis. This postulates that unusual volcanism results from thermal diapirs ("plumes") that originate at the core-mantle boundary and deliver hot material via narrow conduits to Earth's surface....
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.
