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...
This may be Lew Gramer Page 3 of 32 GFD-II 2007: Kelvin-Helmholtz Instabilities a poor assumption, particularly in the case of ocean wave production by wind. However whenever this assumption may limit important results, I’ll try to indication this assumption explicitly. Finally, the class of...
instabilitiesturbulenceSolar wind plasma is supposed to be structured in magnetic flux tubes carried from the solar surface. Tangential velocity discontinuity near the boundaries of individual tubes may result in Kelvin-Helmholtz instability, which may contribute into the solar wind turbulence. While the ...
In most cases, the KH instabilities in the top and bottom sections occur at nearly the same value of Ib, and a time interval separating the two KH processes is not resolved by the bolometer output. In this case, also the NMR alerts signalling the arrival of the turbulent vortex front to...
