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...
Pyroclastic density currents and local topography as seen with the conveyer model
15 Apr 2014 | Contributor(s):: Domenico M. Doronzo
Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...
What good are (PDC) models?
31 Jul 2013 | Contributor(s):: Tomaso Esposti Ongaro
This slides have been presented to the W06 workshop on "Benchmarking volcano models" at IAVCEI 2013 (Kagoshima, Japan). The presentation introduces a hierarchy of fluid dynamics models for pyroclastic density currents (PDC) and the problem of estimating their related uncertainties. A validation...
