  1. 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...
