Stability of shear flows at high Reynolds number has been one of the cornerstones of hydrodynamic stability. A canonical problem which contains the basic features is that of a shear layer - two streams of different velocity owing past each other with different density. Helmholtz18 and Kelvin21 were probably the earliest to consider evolution of disturbances in a stratified vortex sheet. While attempting a more general case Rayleigh27 approximated the shear layer by piecewise-linear velocity profiles.
