Mitigating numerical dissipation in simulations of subsonic turbulent flows
James Watt, Christoph Federrath, Claudius Birke +1
Magnetohydrodynamic (MHD) simulations of subsonic (Mach number~) turbulence are crucial to our understanding of several processes including oceanic and atmospheric flows, the a…
Maximal turbulence as a selection criterion for measure-valued solutions
Christian Klingenberg, Simon Markfelder, Emil Wiedemann
The quest for a good solution concept for the partial differential equations (PDEs) arising in mathematical fluid dynamics is an outstanding open problem. An important notion of so…
BGK model for rarefied gas in a bounded domain
Hongxu Chen, Christian Klingenberg, Marlies Pirner
We study the Bathnagar-Gross-Krook (BGK) equation in a smooth bounded domain featuring a diffusive reflection boundary condition with general collision frequency. We prove that the…
A consistent BGK model with velocity-dependent collision frequency for gas mixtures
Jeff Haack, Cory Hauck, Christian Klingenberg +2
We derive a multi-species BGK model with velocity-dependent collision frequency for a non-reactive, multi-component gas mixture. The model is derived by minimizing a weighted entro…
Thermonuclear explosions of rapidly rotating white dwarfs - II. Detonations
J. M. M. Pfannes, J. C. Niemeyer, W. Schmidt
Context: Superluminous type Ia supernovae (SNe Ia) may be explained by super-Chandrasekhar-mass explosions of rapidly rotating white dwarfs (WDs). In a preceding paper, we showed t…
Thermonuclear explosions of rapidly rotating white dwarfs - I. Deflagrations
J. M. M. Pfannes, J. C. Niemeyer, W. Schmidt +1
Context: Turbulent deflagrations of Chandrasekhar mass White Dwarfs are commonly used to model Type Ia Supernova explosions. In this context, rapid rotation of the progenitor star…
