Abstract:

In der vorliegenden Arbeit wird die Kelvin-Helmholtz-Instabilität in magnetohydrodynamischen Strömungen mit der Methode der Multiplen Skalen analysiert. Die betrachteten Fluide sind inkompressibel oder besitzen eine senkrecht zur Wirbelschicht veränderliche Massendichte, die der Boussinesq-Näherung und konstanten Brunt-Väisälä-Frequenzen genügt. Die Multiple Skalen Analyse führt auf nichtlineare Evolutionsgleichungen der Amplitude der Störungen. Spezielle Lösungen dieser Gleichungen werden präsentiert und die Effekte der Magnetfelder diskutiert.

In the presented work the Kelvin-Helmholtz-Instability in magnetohydrodynamic flows is analyzed with the methods of Multiple Scales. The concerned fluids are incompressible or have a varying density perpendicular to the vortex sheet, which is taken into account using a Boussinesq-Approximation and constant Brunt-Väisälä-Frequencies. The Multiple Scale Analysis leads to nonlinear evolution equations for the amplitude of the perturbations. Special solutions to these equations are presented and the effects of the magnetic fields are discussed.
