Kursinformation

This course will give an introdcution in hydrodynamical and magneto-hydrodynamical fluids, and its applications in astrosphysics. The basic equations of fluid-dynamics will be derived from distribution functions, and the limitation of the fluid equations will be shown. Some analytic example of fluid-dynamics will be dicussed: 1.) the potential theory , which gives descriptive inside in stellar winds and shocks, as well as is the physics of wings. 2.)  Concepts of frozenin magnetic fields and plasma waves, 3.)  hydraulic jumps as analogy  for the "helisophere in a sink", 4.) vortices, like the van Karman street,.

This course is also intended as the basis for sucessive courses on astrophysical shocks, disperion theroy and turbulence.
