  1. Documentation for "Effect of particle entrainment on the runout of pyroclastic density currents"

    08 Sep 2016 | Contributor(s): Kristen Fauria, Michael Manga, Michael Chamberlain

    This is a repository for the data and script used in, "Effect of particle entrainment on the runout of pyroclastic density currents."Here you will find:1. A compilation of splash function experimental data from this study and data that was extracted from seven other studies:...

  2. 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...

  6. 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...
