Shear-flow induced stabilization of kinklike modes

Open publisher page 20 citations

Abstract

The stabilizing effect of a shear flow on a current-driven instability has been studied by means of Kelvin’s representation of spatially-inhomogeneous Galilean transform. Even though conspicuous transient growth may occur, the mixing effect of the shear flow overcomes the instability and damps kinklike modes.
