    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...

  4. Volcanic plume simulation using ATHAM

    12 Oct 2014 | Contributor(s):: Nial Peters, Alex Hoffman, Talfan Barnie, Michael Herzog, Clive Oppenheimer

    These simulation runs were carried out in order to produce sets of synthetic SO2 camera images which could be used for validating SO2 flux calculation algorithms. Results from two model runs are provided: a "closed top" run which had a rigid boundary at the top of the domain, and an...

  7. Plumeria_wd--Fortran open-source version

    out of 5 stars 

    06 Dec 2011 | Contributor(s):: Larry Garver Mastin

    This is an open-source Fortran version of Plumeria, a one-dimensional steady-state model for volcanic plumes. It calculates plume properties such as upward velocity, radius, density, mass fractions of particles, air, water vapor, liquid water and ice, as a function of height in a plume.  The...

  8. Plates vs. Plumes Debate

    out of 5 stars 

    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....

    14 Jul 2010 | | Contributor(s):: Chuck B Connor, Leah Michelle Courtland

    Tephra2 uses the advection diffusion equation to forecast tephra dispersion in a given location based on a user-defined set of eruptive conditions.Tephra2 codes are now maintained on GitHub: https://github.com/geoscience-community-codes/tephra2 Available are:1-processor...
