New developments in the analysis of column-collapse pyroclastic density currents through numerical simulations of multiphase flows
column-collapse pyroclastic density currents numerical simulations of multiphase flows
2015/1/4
A granular multiphase model has been used to evaluate the action of differently sized particles on the dynamics of fountains and associated pyroclastic density currents. The model takes into account t...

Numerical simulations of an ocean/continent convergent system: influence of subduction geometry and mantle wedge hydration on crustal recycling
ocean/continent convergent system Numerical simulations subduction geometry and mantle wedge hydration
2011/9/5
The e ects of the hydration mechanism on continental crust recycling are analyzed through a 2D nite element thermo-mechanical model. Oceanic slab dehydration and consequent mantle wedge hydration are...
Numerical simulations of a three-wave coupling occurring in the ionospheric plasma
Numerical simulations three-wave coupling ionospheric plasma
2009/11/12
We studied a three-wave coupling process occurring in an active experiment of microwave power transmission (MPT) in the ionospheric plasma by performing one-dimensional electromagnetic PIC (Particle-I...
Direct numerical simulations of helical dynamo action:MHD and beyond
Direct numerical simulations helical dynamo action MHD and beyond
2009/11/11
Magnetohydrodynamic dynamo action is often invoked to explain the existence of magnetic fields in several astronomical objects. In this work, we present direct numerical simulations of MHD helical dyn...
Numerical simulations of the charging of dust particles by contact with hot plasmas
Numerical simulations dust particles hot plasmas
2009/11/3
Charging of individual dust particles in contact with hot plasmas is studied by numerical methods. The dust particle is treated as a rigid solid body, composed by either perfectly insulating or conduc...
Low-frequency electrostatic waves in the ionospheric E-region: a comparison of rocket observations and numerical simulations
Ionosphere Space plasma physics
2017/3/22
Low frequency electrostatic waves in the lower
parts of the ionosphere are studied by a comparison of observations
by instrumented rockets and of results from numerical
simulations. Particular atte...
