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, … WebNote, however, that the here-studied convection driven by thermal gradients will be superimposed by solutal convection in an actual growth experiment. Due to the presumably faster dissolution in the upper zone, the density of the solute-containing fluid there will likely increase faster compared to the density of the fluid in the growth zone.

"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 … " - Solutal convection induced by dissolution
