Numerical dissipation and the bottleneck effect in simulations of compressible isotropic turbulence
W. Schmidt, W. Hillebrandt, J. C. Niemeyer
The piece-wise parabolic method (PPM) is applied to simulations of forced isotropic turbulence with Mach numbers . The equation of state is dominated by the Fermi pr…
On self-similarity properties of isotropic turbulence in numerical simulations of the compressible Euler equations
W. Schmidt, W. Hillebrandt, J. C. Niemeyer
We present numerical calculations of the parameters , and associated with the common closures for turbulence production, dissipation and diffusion. In the case of…
Simulations of Turbulent Thermonuclear Burning in Type Ia Supernovae
W. Hillebrandt, M. Reinecke, W. Schmidt +3
Type Ia supernovae have recently received considerable attention because it appears that they can be used as "standard candles" to measure cosmic distances out to billions of light…
Investigating the Flame Microstructure in Type Ia Supernovae
F. K. Roepke, W. Hillebrandt, J. C. Niemeyer
We present a numerical model to study the behavior of thermonuclear flames in the discontinuity approximation. This model is applied to investigate the Landau-Darrieus instability…
Models of Type Ia Supernova Explosions
J. C. Niemeyer, M. Reinecke, W. Hillebrandt
Type Ia supernovae have become an indispensable tool for studying the expansion history of the universe, yet our understanding of the explosion mechanism is still incomplete. We de…
Cosmological consequences of short distance physics
Jens C. Niemeyer
Inflation can act as a space-time microscope for Planck or string scale effects, leaving potentially observable traces in the primordial perturbation spectrum. I discuss two framew…
