Causality and stability in relativistic viscous non-resistive magneto-fluid dynamics

Relativistic Viscous Fluid Dynamics and Non-Equilibrium Entropy

Fluid dynamics corresponds to the dynamics of a substance in the long wavelength limit. Writing down all terms in a gradient (long wavelength) expansion up to second order for a relativistic system at vanishing charge density, one obtains the most general (causal) equations of motion for a fluid in the presence of shear and bulk viscosity, as well as the structure of the non-equilibrium entropy...

Parallel computational magneto-fluid dynamics

In a Priority Program on Massively Parallel Computing, eight Dutch research groups (http://www.phys.uu.nl/~mpr/) cooperate since 1995 to develop new algorithms and software to simulate the non-linear dynamics of thermonuclear, geo-physical, and astrophysical plasmas. As one result of this collaboration, the general-purpose Versatile Advection Codemonstrated excellent scaling properties across a...

Viscous Stability of Relativistic Keplerian Accretion Disks

We investigate the viscous stability of thin, Keplerian accretion disks in regions where general relativistic (GR) effects are essential. For gas pressure dominated (GPD) disks, we show that the Newtonian conclusion that such disks are viscously stable is reversed by GR modifications in the behaviors of viscous stress and surface density over a significantly large annular region not far from th...
