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...

This series of two lectures summarizes the sequence of events asssociated with the 1980-86 eruptions of Mount St Helens, Washington State, USA. It is intended as a refresher for students and researchers.Lipman, Peter W., and Mullineaux, Donal R. (eds.), 1981, The 1980 Eruptions of Mount St....
Pyroclastic density currents and local topography as seen with the conveyer model
15 Apr 2014 | Publications | 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...
