WebDissolution increases the density of the water and so can lead to downwelling convection, which, in turn, substantially increases the rate of dissolution of CO 2 at the water–CO 2 interface. This convective dissolution process has inspired a great deal of academic study over the last 10–15 years; indeed, this wealth of recent research is one of the primary … WebSolutal convection can also induce a pattern on the dissolving interface. We show experimentally with suspended and inclined blocks of salt and sugar, that in a linear stage, …

WebNonlinear solutal convection in a thin liquid layer driven by surface-tension gradients is studied. This effect is referred to as the Marangoni effect. The adsorbing ability of the upper surface is described by the Gibbs adsorption equation. The present analysis is based on the amplitude method, which allows for finite amplitude disturbances.
