Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Note on the Rayleigh waves properties in viscoelastic media
Archives of MechanicsThis paper describes a theory for surface Rayleigh waves propagating in a viscoelastic medium. The Zener model to describe the viscoelastic behavior of the medium is used. This simple model captures both the relaxation and retardation.

On strongly nonlinear vortex/wave interactions in boundary-layer transition [PDF]
The interactions between longitudinal vortices and accompanying waves considered are strongly nonlinear, in the sense that the mean-flow profile throughout the boundary layer is completely altered from its original undisturbed state.
