A robust method for calculating interface curvature and normal vectors using an extracted local level set
(Journal article; Peer reviewed, 2014)The level-set method is a popular interface tracking method in two-phase flow simulations. An often-cited reason for using it is that the method naturally handles topological changes in the interface, e.g. merging drops, ... -
An adaptive Cartesian embedded boundary approach for fluid simulations of two- and three-dimensional low temperature plasma filaments in complex geometries
(Peer reviewed; Journal article, 2019)We review a scalable two- and three-dimensional computer code for low-temperature plasma simulations in multi-material complex geometries. Our approach is based on embedded boundary (EB) finite volume discretizations of ... -
Computation of three-dimensional three-phase flow of carbon dioxide using a high-order WENO scheme
(Journal article; Peer reviewed, 2017)We have developed a high-order numerical method for the 3D simulation of viscous and inviscid multiphase flow described by a homogeneous equilibrium model and a general equation of state. Here we focus on single-phase, ... -
Enhanced multiscale restriction-smoothed basis (MsRSB) preconditioning with applications to porous media flow and geomechanics
(Peer reviewed; Journal article, 2021)A novel method to enable application of the Multiscale Restricted Smoothed Basis (MsRSB) method to non M-matrices is presented. The original MsRSB method is enhanced with a filtering strategy enforcing M-matrix properties ... -
Stochastic and self-consistent 3D modeling of streamer discharge trees with Kinetic Monte Carlo
(Peer reviewed; Journal article, 2024)This paper contains the foundation for a new Particle-In-Cell model for gas discharges, based on Îto diffusion and Kinetic Monte Carlo (KMC). In the new model the electrons are described with a microscopic drift-diffusion ... -
Transient electrohydrodynamic flow with concentration-dependent fluid properties: Modelling and energy-stable numerical schemes
(Peer reviewed; Journal article, 2020)Transport of electrolytic solutions under influence of electric fields occurs in phenomena ranging from biology to geophysics. Here, we present a continuum model for single-phase electrohydrodynamic flow, which can be ...
