On the formation and recurrent shedding of ligaments in droplet aerobreakup
Benedikt Dorschner, Luc Biasiori-Poulanges, Kevin Schmidmayer +2
The breakup of water droplets when exposed to high-speed gas flows is investigated using both high-magnification shadowgraphy experiments as well as fully three-dimensional numeric…
Near-surface dynamics of a gas bubble collapsing above a crevice
Theresa Trummler, Spencer H. Bryngelson, Kevin Schmidmayer +3
The impact of a collapsing gas bubble above rigid, notched walls is considered. Such surface crevices and imperfections often function as bubble nucleation sites, and thus have a d…
MFC: An open-source high-order multi-component, multi-phase, and multi-scale compressible flow solver
Spencer H. Bryngelson, Kevin Schmidmayer, Vedran Coralic +3
MFC is an open-source tool for solving multi-component, multi-phase, and bubbly compressible flows. It is capable of efficiently solving a wide range of flows, including droplet at…
An assessment of multicomponent flow models and interface capturing schemes for spherical bubble dynamics
Kevin Schmidmayer, Spencer H. Bryngelson, Tim Colonius
Numerical simulation of bubble dynamics and cavitation is challenging; even the seemingly simple problem of a collapsing spherical bubble is difficult to compute accurately with a…
ECOGEN, an open-source tool dedicated to multiphase compressible multiphysics flows
Kevin Schmidmayer, Antoine Marty, Fabien Petitpas +1
This paper presents a new multiphase flow code, cast under an open-source GNU license. The main characteristics of the different flow models are given, then the numerical method us…
