WebSalt fingering. Salt fingering is a mixing process, example of double diffusive instability, that occurs when relatively warm, salty water overlies relatively colder, fresher water. It is driven by the fact that heated water diffuses more readily than salty water. A small parcel of warm, salty water sinking downwards into a colder, fresher ... WebJun 4, 1998 · The growth of fingering heat and salt fluxes in this system is shown to be limited by the instability of fingering cells, and an equilibrium state is achieved when the …
WebJan 1, 1995 · The "collective instability" mechanism could be responsible for this phenomena "split", because the layer splitting occurred when the Stern Number is much greater than order 1. ... a salt finger ... WebMar 1, 2003 · However, the stability of salt-fingers is itself not yet fully understood. Since Stern (1969) proposed a collective instability theory, salt-finger instability has been investigated in various contexts (Holyer, 1981, Veronis, 1987, Howard and Veronis, 1987). The Stern number criterion seems to be sufficient to. Acknowledgments
WebJun 25, 2005 · This motion appears to be related to the secondary instability found in unsheared, unbounded, salt fingers (Holyer, 1984;Stern and Simeonov, 2005). [Both … WebMar 1, 2011 · The new thermohaline-shear mode is analogous to the well-known oscillatory collective instability , which is driven by the interaction between salt finger transport and internal waves. The vertical temperature ( T ) and salinity ( S ) fluxes due to salt fingering are controlled by the vertical finescale T – S gradients.
WebSep 1, 2000 · In section 4, we consider the effect of a nonconstant salt finger flux ratio and show that using either the formulation due to Stern (1975) or that due to Schmitt (1979a) leads to a high wavenumber “UV” instability different from the classical intrusive instability, but qualitatively similar to that discussed by Huppert (1971).
