Flow of a vortex-pair street and the evolution of salt fingers.
We considered the geometry of a double row of vortex pairs in an ideal fluid, and studied the evolution of salt fingers from the geometry systematically. This study illustrates the mechanism of the generation of large-scale convective cells at the final stage of the fingering instability. We discuss why in the growth of double-diffusive salt fingers the emergence of such large convection cells has been implicated phenomenologically as an onset to turbulence, terminating the finger growth.
