  3. PYFLOW_2.0. A new tool for estimating the impact parameters and the deposition rate and time of dilute PDCs based on field data

    22 Nov 2017 | Contributor(s):: Fabio Dioguardi, Daniela Mele, Pierfrancesco Dellino

    PYFLOW_2.0 is a hazard tool for the calculation of the impact parameters of dilute pyroclastic density currents (DPDCs). DPDCs represent the dilute turbulent type of gravity flows that occur during explosive volcanic eruptions; their hazard is the result of their mobility and the capability...

    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...

  9. Numerical simulations (TOUGH2) to quantify crater lake seepage: a case study for Laguna Caliente, Poás Volcano (Costa Rica)

    23 Aug 2013 | Contributor(s):: massimo nespoli, micol todesco, dmitri rouwet, maurizio bonafede, raul mora-amador

    Volcanic lakes are different from the common reservoirs of meteoric origin because of the interaction with the hydrothermal system of the volcano. The hot fluids (gas + liquid) of volcanic origin rise through the bottom of the lake resulting in strong acidic water and a variable temperature...

  10. Observational constraints for lava flow models

    26 Jul 2013 | Contributor(s):: Einat Lev

    A presentation given at the IAVCEI 2013 workshop for benchmarking of mass flows. The presentation is focusing on natural and experimental observations relevant to benchmarking of lava flows: temperature, velocity and flux rate, material properties, crust cover,
