On floating point precision in computational fluid dynamics using OpenFOAM
F. Brogi, S. Bnà, G. Boga +3
Thanks to the computational power of modern cluster machines, numerical simulations can provide, with an unprecedented level of details, new insights into fluid mechanics. However,…
A theoretical framework and the experimental dataset for benchmarking numerical models of dilute pyroclastic density currents
Matteo Cerminara, Ermanno Brosch, Gert Lube
The aim of this document is to define a Pyroclastic Density Currents (PDCs) benchmark based on a large-scale experiment to be used with numerical models at different levels of comp…
ASHEE: a compressible, equilibrium-Eulerian model for volcanic ash plumes
Matteo Cerminara, Tomaso Esposti Ongaro, Luigi Carlo Berselli
A new fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-d…
The Multiphase Buoyant Plume Solution of the Dusty Gas Model
Matteo Cerminara
Starting from the balance equations of mass, momentum and energy we formulate an integral 1D model for a poly-disperse mixture injected in the atmosphere. We write all the equation…
Ash plume properties retrieved from infrared images: a forward and inverse modeling approach
Matteo Cerminara, Tomaso Esposti Ongaro, Sébastien Valade +1
We present a coupled fluid-dynamic and electromagnetic model for volcanic ash plumes. In a forward approach, the model is able to simulate the plume dynamics from prescribed input…
DNS of compressible multiphase flows through the Eulerian approach
Matteo Cerminara, Luigi Carlo Berselli, Tomaso Esposti Ongaro +1
In this paper we present three multiphase flow models suitable for the study of the dynamics of compressible dispersed multiphase flows. We adopt the Eulerian approach because we f…
Direct numerical simulation of a compressible multiphase flow through the fast Eulerian approach
Matteo Cerminara, Luigi Carlo Berselli, Tomaso Esposti Ongaro +1
Our work is motivated by the analysis of ash plume dynamics, arising in the study of volcanic eruptions. Such phenomena are characterized by large Reynolds number (exceeding …
Disperse two-phase flows, with applications to geophysical problems
Luigi Carlo Berselli, Matteo Cerminara, Traian Iliescu
In this paper we study the motion of a fluid with several dispersed particles whose concentration is very small (smaller than ), with possible applications to problems com…
