Mixing in a moderately sheared, diffusively unstable layer
We study mixing in a thermohaline staircase by means of direct numerical simulations (DNS). A single saltfingering layer is modeled as a diffusively unstable shear layer of hyperbolic tangent form. Our main interest is the influence of shear, and we focus on what we call the “moderate shear” case. This is the regime where shear is strong enough to produce Kelvin-Helmholtz (KH) instability, but ...
متن کاملMixing in a Moderately Sheared Salt-Fingering Layer
Mixing due to sheared salt fingers is studied by means of direct numerical simulations (DNS) of a doublediffusively unstable shear layer. The focus is on the ‘‘moderate shear’’ case, where shear is strong enough to produce Kelvin–Helmholtz (KH) instability but not strong enough to produce the subharmonic pairing instability. This flow supports both KH and salt-sheet instabilities, and the objec...

15 صفحه اولOn mixing and transport at a sheared density interface
Mixing and transport of a stratifying scalar are investigated at a density interface imbedded in a turbulent shear flow. Steady-state interfacial shear flows are generated in a laboratory water channel for layer Richardson numbers, Ri, between about 1 and 10. The flow field is made optically homogeneous, enabling the use of laser-induced fluorescence with photodiode array imaging to measure the...
متن کاملeffects of first language on second language writing-a preliminary contrastive rhetoric study of farsi and english
to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
