On the possibility of wave-induced chaos in a sheared,stably stratified fluid layer
wave-induced chaos sheared,stably stratified fluid layer
2009/11/16
Shear flow in a stable stratification provides a waveguide for internal gravity waves. In the inviscid approximation, internal gravity waves are known to be unstable below a threshold in Richardson nu...
We present a numerical study of the generation and evolution of a mixed layer in a stably stratified layer of Boussinesq fluid. We use an external forcing in the equation of motion to model the experi...
A centre manifold approach to solitary waves in a sheared,stably stratified fluid layer
centre manifold approach solitary waves stratified fluid layer
2009/11/16
The centre manifold approach is used to derive an approximate equation for nonlinear waves propagating in a sheared, stably stratified fluid layer. The evolution equation matches limiting forms derive...
A theoretical model of a wake of a body towed in a stratified fluid at large Reynolds and Froude numbers
theoretical model stratified fluid large Reynolds Froude numbers

The objective of the present paper is to develop a theoretical model describing the evolution of a turbulent wake behind a towed sphere in a stably stratified fluid at large Froude and Reynolds number...
