Abstract

Direct numerical simulations of two-dimensional fingering convection are presented. They show the growth of a finger-zone from a region of high gradients of temperature and salinity set in the initial conditions and the appearance of large-scale convective cells in the homogeneous layers above and below it. The interaction between the finger-zone and the convection is described and the vertical fluxes are compared with a theoretical scaling law.
