Analysis and simulations of droplet generation regimes in a coaxial microfluidic device
Alessio Innocenti, Andrea Poggi, Simone Camarri +1
The generation of microdroplets via segmentation in microfluidic devices is of interest in many applications, from biochemical to pharmaceutical. This technique permits indeed much…
Flashback propensity due to hydrogen blending in natural gas: sensitivity to operating and geometrical parameters
Filippo Fruzza, Rachele Lamioni, Alessandro Mariotti +2
Hydrogen has emerged as a promising option for promoting decarbonization in various sectors by serving as a replacement for natural gas while retaining the combustion-based convers…
Multigrid sequential data assimilation for the large-eddy simulation of a massively separated bluff-body flow
Gabriel Moldovan, Alessandro Mariotti, Laurent Cordier +3
The potential for data-driven applications to scale-resolving simulations of turbulent flows is assessed herein. Multigrid sequential data assimilation algorithms have been used to…
A Lagrangian probability-density-function model for collisional turbulent fluid-particle flows. II. Application to homogeneous flows
Alessio Innocenti, Rodney O Fox, Maria Vittoria Salvetti +1
The Lagrangian probability-density-function model, proposed in Part I for dense particle-laden turbulent flows, is validated here against Eulerian-Lagrangian direct numerical simul…
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 …
Quantification of errors in large-eddy simulations of a spatially-evolving mixing layer
Marcello Meldi, Maria Vittoria Salvetti, Pierre Sagaut
A stochastic approach based on generalized Polynomial Chaos (gPC) is used to quantify the error in Large-Eddy Simulation (LES) of a spatially-evolving mixing layer flow and its sen…
Intrinsic filtering errors of Lagrangian particle tracking in LES flow fields
F. Bianco, S. Chibbaro, C. Marchioli +2
Large-Eddy Simulations (LES) of two-phase turbulent flows exhibit quantitative differences in particle statistics if compared to Direct Numerical Simulations (DNS) which, in the co…
Statistical properties of an ideal subgrid-scale correction for Lagrangian particle tracking in turbulent channel flow
Federico Bianco, Sergio Chibbaro, Cristian Marchioli +2
One issue associated with the use of Large-Eddy Simulation (LES) to investigate the dispersion of small inertial particles in turbulent flows is the accuracy with which particle st…
Some issues concerning Large-Eddy Simulation of inertial particle dispersion in turbulent bounded flows
C. Marchioli, M. V. Salvetti, A. Soldati
The problem of an accurate Eulerian-Lagrangian modeling of inertial particle dispersion in Large Eddy Simulation (LES) of turbulent wall-bounded flows is addressed. We run Direct N…
