Abstract

In tokamak experiments with strong neutral beam injection, equilibrium flows can become substantial, for example, flows of the order of the speed of sound have been measured in PDX1 and ISX-B2. So far, MHD stability theory has largely been concerned with static equilibria and the knowledge of MHD stability for equilibria with flows is very incomplete. Mass flows render the linearised MHD equations non selfadjoint and the energy principle no longer gives simple sufficient condition for instability. Thus the stability considerations become considerably more involved than in the static case. Here, we consider the ideal MHD stability of a cylindrical equilibrium with sheared flows in the axial and azimuthal directions.
