Structure-preserving approximation of the non-isothermal Cahn-Hilliard system based on the entropy equation

Aaron Brunk, Dennis Höhn, Mária Lukáčová-Medvidová

We propose and analyze a structure-preserving approximation of the non-isothermal Cahn-Hilliard equation using conforming finite elements for the spatial discretization and a probl…

Convergence of a Hyperbolic Thermodynamically Compatible Finite Volume scheme for the Euler equations

Michael Dumbser, Mária Lukáčová-Medvid'ová, Andrea Thomann

We study the convergence of a novel family of thermodynamically compatible schemes for hyperbolic systems (HTC schemes) in the framework of dissipative weak solutions, applied to t…

Provably fully discrete energy-stable and asymptotic-preserving scheme for barotropic Euler equations

Megala Anandan, Mária Lukáčová-Medvid'ová

We develop structure-preserving finite volume schemes for the barotropic Euler equations in the low Mach number regime. Our primary focus lies in ensuring both the asymptotic-prese…

Solving Random Hyperbolic Conservation Laws Using Linear Programming

Shaoshuai Chu, Michael Herty, Maria Lukacova-Medvidova +1

A novel structure-preserving numerical method to solve random hyperbolic systems of conservation laws is presented. The method uses a concept of generalized, measure-valued solutio…

Numerical Study of Random Kelvin-Helmholtz Instability

Alina Chertock, Michael Herty, Arsen S. Iskhakov +3

In this paper, we study random dissipative weak solutions of the compressible Euler equations in the Kelvin-Helmholtz (KH) instability. Motivated by the fact that weak entropy solu…
