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…
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…
