Workshop I: Astrophysical Fluid Dynamics

April 4 - 9, 2005


The unifying theme of this workshop is the computational approach to astrophysical fluids, be they plasmas, neutral clouds, or some mix of the two. Emphasis will be placed on 1) the range of astrophysical applications appropriate to each computational technique, 2) the methodologies developed for including gravity, magnetic fields, radiation transport, dust, energy sinks and sources, and other physical processes, and 3) the algorithmic responses developed to avoid instabilities and unphysical dissipation in the computations. Topics to include:

  • hydrodynamics and magnetohydrodynamics.

o    accretion disk instabilities

o    jet formation

o    molecular cloud support

o    origin & growth of cosmic magnetic fields

o    evolution of galactic magnetic fields

o    planetary nebulae

o    astrophysical pair plasmas

  • multi-phase flows:

o    dust and gas in accretion disks & in radiatively-driven winds

  • turbulence, convection, chaos
  • evolution of molecular clouds

o    interstellar chemistry

o    turbulence

  • star formation

o    first generation

o    current star formation

o    star formation in high-pressure environments

o    multiple star and cluster formation

  • supernovae and novae

o    detonations, flame propagation

o    nuclear reaction networks

  • thermal pulses
  • r,s, and p processes
  • computational issues:

o    breakdown of the fluid approximation at small scales, low densities

o    comparisons of particle versus finite difference methodologies

o    advances in adaptive mesh refinement techniques

o    test cases for codes
