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,…
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…
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 …
