Laboratory Simulation of Fluid Dynamical Process Related to Winter Arctic Leads

Abstract

A comprehensive series of experiments were carried out to investigate the layered convection that occurs in linearly salt-stratified fluids subjected to destabilizing buoyancy fluxes, in particular heating from below. Unlike previous work, turbulence in the convecting layers was explicitly taken into account in modelling heat and salt transports through these layers. It was shown theoretically that the thicknesses of convecting layers can be parameterized. Accordingly, expressions were derived for thicknesses of the first and the rest of the convecting layers. Experimental results were found to be in good agreement with the proposed predictions.
