The Godunov SPH describes the formation and evolution of the fingers due to the combinations of Rayleigh-Taylor, Richtmyer-Meshkov, and Kelvin-Helmholtz instabilities. The blob test result coincides well with the results of the grid-based codes. An inaccurate handling of a density gradient in the...
Kelvin–Helmholtz instabilities can form due to a number of mechanisms. Under strong forcing conditions and as thethermoclineapproaches mid-depth (> ∼0.8 and > ∼0.3), the seiche-induced currents will be sufficiently strong to overcome the stabilizing effects of stratification. Shear instabilities...
Finally, molecular viscosity is likely to play an important role in small-scale instabilities: below we will try to decompose its stabilizing or destabilizing effect in the absence of stratification. Lew Gramer Page 5 of 32 GFD-II 2007: Kelvin-Helmholtz Instabilities 3. Sufficiency of two ...
In rotating $$^3$$ He superfluids, the Kelvin–Helmholtz (KH) instability of the AB interface has been found to follow the theoretical model above $$0
Twisted magnetic flux tubes can be unstable to Kelvin-Helmholtz instability when they move with small speed relative to main solar wind stream, then the Kelvin-Helmholtz vortices may significantly contribute into the solar wind turbulence.Zaqarashvili, T V; V枚r枚s, Z; Zhelyazkov, I...
The linear Kelvin-Helmholtz stability regime of two radiating fluids in relative motion is discussed. The study is carried out in plane geometry and in the vortex-sheet approximation. Attention is focused on the effects of radiation losses on the instability pattern: it is found that the principal...

Definition Kelvin -Helmholtz instability arises because of shear along an interface between two different fluids. Being related to turbulence and transition phenomena, it also describes the onset of ocean wave formation, jetting instabilities, and cloud formation. In microfluidics, it is commonly seen ...
The Kelvin–Helmholtz instability (KHI) is a ubiquitous phenomenon across the Universe, observed from 500 m deep in the oceans on Earth to th
