Evidence of the critical layer mechanism in growing wind waves
Highly resolved laboratory measurements of the airflow over wind-generated waves are
examined using a novel wave growth diagnostic that quantifies the presence of Miles' critical …

Asymptotic interpretation of the Miles mechanism of wind-wave instability
When wind blows over water, ripples are generated on the water surface. These ripples can
be regarded as perturbations of the wind field, which is modelled as a parallel inviscid flow …

Understanding the destabilizing role for surface tension in planar shear flows in terms of wave interaction
Both surface tension and buoyancy force in stable stratification act to restore perturbed
interfaces back to their initial positions. Hence, both are intuitively considered as stabilizing …

On the scaling and critical layer in a turbulent boundary layer over a compliant surface
Simultaneous time-resolved measurements of wall deformation and the 3-D velocity field in
boundary layers over a compliant surface are performed by integrating Mach Zehnder …

A generalized action-angle representation of wave interaction in stratified shear flows
In this paper we express the linearized dynamics of interacting interfacial waves in stratified
shear flows in the compact form of action-angle Hamilton's equations. The pseudo-energy …

Instability of a smooth shear layer through wave interactions
JR Carpenter, A Guha - Physics of Fluids, 2019 - pubs.aip.org
Wave interaction theory can be used as a tool to understand and predict instability in a
variety of homogeneous and stratified shear flows. It is, however, most often limited to …

Effect of free surface on submerged stratified shear instabilities
In this paper, we have considered the effects of the shallowness of the domain as well as the
air–water free surface on the stratified shear instabilities of the fluid underneath. First, we …
