Open publisher page 8 citations

Abstract

The effect of background vorticity on the instability of a vortex sheet is theoretically described by an inviscid linear stability analysis. The background vorticity increases the growth rate of the deformed vortex sheet whose vorticity is of the same sign as the background vorticity.
