Their topics include solitary wave generation due to passage through the local resonance, asymptotic expansions of singular perturbation theory, the Kelvin-Helmholtz instability
, and nonlinear Cauchy problems for elliptic equations.
However they quickly realized the cause was Kelvin-Helmholtz instability
, where fluids moving at different speeds shear apart and form whirls.

There is no detailed information about the flame front and about the vortex shedding and development of the Kelvin-Helmholtz instability in the wake of the injector post available, which is important for turbulence and turbulent combustion modeling.
The second test case is characterized by a strong interplay of two processes: the formation of the [H.sub.2]O layer and the onset of the strong Kelvin-Helmholtz instability occurring due to the large density and velocity gradients in the [H.sub.2]O layer.
Where there is large shear force across an initial amplitude between two-component fluids, the interface is unstable, which is called Kelvin-Helmholtz instability
. According to the results from Lee and Kim .
The Kelvin-Helmholtz instability occurs when there is a relative motion between the fluid layers of different physical parameters.

In one interpretation the knots derive from shock waves excited by the so-called Kelvin-Helmholtz instability
- an undulating, wavelike disturbance that occurs where a supersonic fluid brushes past its slower-moving surroundings.
